Bound By Duty

Assignment: Single Mom Surveillance

The Military K-9 Unit series continues

Her serial killer brother’s escaped—and it’s single mom Zoe Sullivan who’s under suspicion! Sgt. Linc Colson trusts two things: his instincts and his Rottweiler K-9 partner, Star—and certainly not the pretty face he’s assigned to monitor. He’s done everything to keep her from getting under his skin—now he must stop those who want to put her six feet under.

VALERIE HANSEN was thirty when she awoke to the presence of the Lord in her life and turned to Jesus. She now lives in a renovated farmhouse in the breathtakingly beautiful Ozark Mountains of Arkansas and is privileged to share her personal faith by telling the stories of her heart for Love Inspired. Life doesn’t get much better than that!

Zoe gazed down at the dog. “She’s beautiful.”

“And intelligent and trained to be lethal, if necessary,” Linc cautioned.

“I don’t doubt that for a second.” Meeting Star’s upturned face with a tender look of her own, Zoe dangled the tips of her fingers over the edge of the box. The dog noticed but didn’t seem upset, so she took a chance and wiggled them.

Star had apparently realized she wasn’t a danger because she sniffed Zoe’s fingers, then gave them a quick lick.

“Are you trying to recruit her to the dark side?”

“Not at all. Actually, I’m very impressed with Star. She’s a lot smarter than you security forces people are. She’s already decided I’m one of the good guys around here.”

“Then it’s a good thing she’s not the one in charge.”

God is our refuge and strength, a very present help in trouble. Therefore we will not fear.

—Psalms 46:1–2

Dear Reader,

This is a story of redemption and forgiveness. Even when our past is troubled, there is always hope, always a way to go on. Personally, I don’t know how anyone copes daily without a saving faith in Jesus Christ. He has brought me through many trials when I saw only dark clouds and imagined no rainbows, no possibilities of future happiness.

The struggles of Zoe and Linc were intensified because they both dwelled on an unhappy past rather than accepting the new chance for love that was awaiting them. We can’t go back and fix mistakes—and would probably make things worse if we tried. Each challenge is a way to learn and grow, each new day a precious gift. We only need to accept God’s love and forgiveness, trust Him and willingly place the rest of our lives in His care.

I can be reached by email at Val@ValerieHansen.com, or via my website, www.valeriehansen.com.

Blessings,

Valerie

Special thanks to former air force sergeant Nancy N. for her advice and to our pastor, John, who also served, as did his son.

Terri Reed, Dana Mentink, Maggie K. Black, Lenora Worth, Lynette Eason, Laura Scott, Shirlee McCoy and I all did our best to support each other’s efforts and learn proper air force protocol for this series. It was difficult, but we gave it our all.

God bless the men and women of our current military who daily give far more and those who have sacrificed in the past to keep us free. We are grateful beyond words.

About the Publisher

ONE

She was being watched. Constantly. Every fiber of her being knew it. Lately, she felt as though she was the defenseless prey and packs of predators were circling her and her helpless little boy, which was why she’d left Freddy at home with a sitter. Were things as bad as they seemed? It was more than possible, and Staff Sergeant Zoe Sullivan shivered despite the warm spring day.

Scanning the busy parking lot as she left the Canyon Air Force Base Exchange with her purchases, Zoe quickly spotted one of the Security Forces investigators. Her pulse jumped, and hostility took over her usually amiable spirit. The K-9 cop in a blue beret and camo ABU—Airman Battle Uniform—was obviously waiting for her. She bit her lip. Nobody cared how innocent she was. Being the half sister of Boyd Sullivan, the escaped Red Rose Killer, automatically made her a person of interest.

Zoe clenched her teeth. There was no way she could prove herself, so why bother trying? She squared her slim shoulders under her blue off-duty T-shirt and stepped out, heading straight for the Security Forces man and his imposing K-9, a black-and-rust-colored rottweiler.

Clearly, he saw her coming because he tensed, feet apart, body braced. In Zoe’s case, five and a half feet was the most height she could muster. The dark-haired tech sergeant she was approaching looked to be quite a bit taller.

He gave a slight nod as she drew near and greeted her formally. “Sergeant Sullivan.”

Linc Colson’s firm jaw, broad shoulders and strength of presence were familiar. They had met during a questioning session conducted by Captain Justin Blackwood and Master Sergeant Westley James shortly after her half brother had escaped from prison.

Zoe stopped and gave the cop an overt once-over. “Can I help you with something, Sergeant Colson?”

“No, ma’am.”

A cynical smile teased at one corner of her mouth. “Oh? Then why is it you’re always following me? Don’t you ever get a day off?”

“Just doing my job, Sergeant.”

She knew he was right, but it galled her to be the object of futile efforts when base Security Forces could have been using their manpower to figure out who at Canyon Air Force Base was really cooperating with Boyd. How long were they going to continue disrupting her life and work? A wryly humorous thought intruded, and she chuckled.

Colson stared. The muscular K-9 at his side tensed. “What’s so funny?”

Zoe waved her hands in dismissal as best she could with the canvas grocery tote handles looped over her forearms. “Relax, Sergeant. I wasn’t laughing at you. I was just picturing you guys trying to track me when I’m giving flying lessons. How are you at piloting a T-38 in close formation?”

She was relieved to note he was having difficulty containing his own smile. His mouth stayed put, but there was no denying a spark in his green eyes.

“I’d wait for you on the ground,” he said. “Or outside the simulator.”

Sobering, Zoe shook her head slowly, her light brown ponytail swinging. “I don’t suppose it would do me any good to take an oath that I haven’t seen Boyd since the last time I visited him in prison.”

“That’s not for me to say.”

“No, I don’t suppose it is.” An eyebrow arched above her hazel eyes. “What if it were? Would you be willing to at least give me the benefit of the doubt instead of condemning me outright?”

To her surprise and disappointment, he said, “No.”

“So much for the famous air force camaraderie,” Zoe muttered. Louder, she said, “Fine,” shouldered past him and started up the sidewalk toward Base Boulevard.

He turned slightly as she passed. “Those bags look heavy. Why didn’t you call a cab after you bought so much?”

“It’s a beautiful spring day in the heart of Texas,” she snapped back. “Walking is a pleasure.”

“If you say so.”

Righteous indignation surged, and she picked up her pace. She couldn’t stop the base cops from shadowing her, but she didn’t have to make it easy. If her conscience hadn’t kept kicking up, she would have enjoyed her impromptu plan to ditch this one even more.

Instead of looking back to see how far ahead she was getting, she checked the reflections in the rear window of a bus that was unloading green recruits, probably for a tour of the impressive shopping facilities at the Base Exchange.

It looked as if Sergeant Colson was trailing her by at least a hundred yards. Good. Her smile returned. She shouldered her way through the milling group of men and women gathered on the sidewalk, then ducked in front of the idling bus, keeping it between her and the K-9 cop for as long as she could before darting around the far end of the stores in the Exchange and breaking into a run.

The moment she saw the warehouse complex behind the stores she knew exactly what to do next. She slipped between two of them and paused to catch her breath. Yes, the K-9 could and would track her. But in the meantime, she intended to enjoy thwarting his handler for a few minutes. Let Colson wonder where she was and what she was up to. Base personnel had already painted her as a clever criminal, a person to be avoided and mistrusted. A contrary side to her nature insisted on payback.

She ducked around a second corner, tried a side door to one of the warehouse buildings, found it unlocked and bolted through, lowering her sacks of groceries to the floor as she pressed her back to the inside of the steel door.

Breathless, Zoe stared into the darkness of the vast windowless storage area and waited for her night vision to improve.

This is wrong, her conscience insisted.

Was she finished playing games? Not quite. Leaving behind her purchases, she flipped the lock on the door to secure it and began to edge past pallets of boxes stacked in rows, looking for a different exit.

The sudden whirring of a motor stopped her in her tracks. Somebody was raising the overhead bay doors at the far end. Light crept below the broad edge of the moving panels. Then they stopped, leaving a gap of about three feet between the floor and the base of the door.

Zoe didn’t move. Hardly breathed. Had Sergeant Colson located her already? Wow, he was good at tracking. Or, at least, his dog was. She was preparing to step forward and reveal herself—until she realized she wasn’t seeing a K-9.

Instead, a man in camo and combat boots and a woman wearing a skirt and high heels ducked beneath the hanging door. All Zoe could see clearly was their feet and lower legs, but it was obvious she’d given Colson too much credit. He hadn’t found her. This was probably nothing more than a lovers’ tryst.

Voices reached her but were too muted to understand. She was about to back away and give the couple privacy when she saw a muzzle flash and heard the reverberation of a gunshot.

Instinct made her duck and cover her ears. Self-preservation kept her down while every hair at the nape of her neck prickled and her body trembled, willing her to run yet keeping her feet leaden. She could barely breathe.

The female figure was crumpling to the floor. Zoe could see blood spreading across the back of a reddish-haired woman’s light-colored blouse. The shooter bent over her, his gun at the ready, a black ski mask hiding his features.

Help! She had to get help. Trembling, Zoe pulled her cell phone from the pocket of her PT shorts. Its lit screen and beeps of dialing were her undoing. As the victim lay still, bleeding and perhaps dying, the assailant straightened, wheeled to face the noise and started to move toward Zoe.

He was coming for her. She was next!

* * *

Linc Colson was concentrating, his jaw clenched, every nerve taut, as he followed K-9 Star. The rottweiler was as good as they came, and he trusted her tracking skills implicitly. That was why when she began to bark and paw at a closed warehouse door, he drew his sidearm and immediately tried the handle. Locked. And far too sturdily made to kick open.

He’d reached for the mic clipped to his shoulder, intending to report the evasive actions of his assigned suspect when a C-130 passing overhead forced a delay. He could hardly hear Star’s barking over the roar of those engines, let alone hope to be able to transmit clearly. He just hoped Sergeant Sullivan hadn’t run off to meet her murderous brother.

Linc jiggled the door handle again to no avail. He had just let it go when the heavy door swung open and a body slammed into his chest. Zoe Sullivan! Pushing her away, he commanded Star to sit and stay while one hand hovered over his holster and he faced his quarry.

Gasping, she raised both hands, palms out. “Don’t shoot. It’s me.”

“I can see that.” He had to shout at her to make himself heard over the fading roar of the cargo plane.

When she reached out to him, he took additional evasive action. “Stay where you are.”

“No! You don’t understand.”

Her voice was shrill. Different than before. She sounded frightened. Well, too bad. “If you didn’t want to get in more trouble, you shouldn’t have tried to ditch me.” He peered past her. “Where’s Boyd?”

“How should I know?”

Judging by the way she kept shaking her head, waving her hands and gaping at him, she’d scared herself more than she’d worried him. Good. It served her right.

“I’m sorry. I promise I won’t do it again, but...”

“You sure won’t.” He signaled his dog to stand guard. “No more special courtesy for you, Sergeant Sullivan. From now on, I’m your shadow. You got that?”

“Fine. Then follow me.”

She turned and ducked back through the open door so quickly only Star kept up. Linc shouted, “Stop!” But the flight instructor kept right on going, stumbling when Star got in front of her to try to block her progress.

Linc grabbed a fistful of the back of Zoe’s shirt and yanked her back outside. “Oh, no, you don’t!”

She struggled against his hold. “Let me go. She may not be dead yet!”

“Who may not be dead? What kind of games are you playing now?”

“No games. I saw a woman get shot.” Staggering to keep her balance, she pointed with her whole arm. “Right in there. The shot echoed. You must have heard it, too.”

“Not over the engines of a C-130.” Linc drew his gun and took a defensive stance. “If you’re lying...”

“I’m not. I saw the shooting with my own eyes. When I tried to phone for help, the killer spotted me. I had to run for my life.” Her lips trembled. “And, no, it wasn’t Boyd. At least not this time.”

Either the flight instructor was telling the truth or she deserved an Oscar for acting, Linc decided. Not only was she shaking all over, his own nerves had begun firing wildly. The back of his neck tingled and he sensed danger the way he had in combat when trying to outwit a hidden enemy.

Pushing her aside with his free arm, he aimed blindly into the dark warehouse. “How could you see a thing in there?”

“The—the loading door at the other end was partly open when it all happened. The guy must have closed it after he shot her.”

Linc reached for his radio, reported the possible crime and was assured of backup, then instructed Zoe. “You stay out here. I’m going in to see if I can find the lights.”

“No way. Suppose the shooter gets behind you.”

“Star would alert me.”

“I still think I should go along. I can help.”

“The dog can do it better,” Linc insisted.

“I give up. I’m scared, okay? My little boy needs me, and you know I’m unarmed. The shooter knows I saw him. I don’t want to wait out here by myself.”

He could hear her rapid breathing, feel her fear. “That’s the first totally honest thing I’ve heard you say,” Linc replied. “All right. But stay close behind me in case I have to fire.”

“Gladly.”

Stepping inside, Linc placed each boot as silently as possible. He moved ahead in a half crouch in order to present a smaller target. Star preceded him. Zoe followed.

A swishing, fluttering noise from above startled all three of them. Zoe let out a tiny gasp but didn’t scream, impressing him, despite his lingering anger at her foolish tricks. Star paused for a moment, then looked forward again. “A bird in the rafters,” Linc whispered.

Although his human companion didn’t react, he continued to feel her presence, as if his actual shadow had substance. He’d have waited for backup if Sullivan hadn’t mentioned a victim. Given that complication, he needed to reach the scene and assess any injuries. Quickly.

Pausing, Linc waved his palm in front of Star’s nose, then held it up to stop Zoe, too. “Stay here. The panel for the lights is right ahead. When I turn them on, I don’t want you to be out in the open.”

“Will your dog panic and bite me if you leave?” Zoe whispered.

Under other circumstances Link would have chuckled. “Not unless I tell her to, so don’t run away again.”

Sergeant Sullivan’s muttered reply faded to nothing as Linc moved forward. His sight had adjusted to the darkness enough to tell where he was but not enough to spot hidden attackers.

He reached for the panel and flipped the switches. Banks of overhead fluorescent lights flickered, then steadied, illuminating the entire warehouse.

Linc’s first act was to ensure that there was no imminent threat. His gaze swept the building contents, then came to rest on Zoe. Star was seated at her feet, panting and totally unconcerned, meaning she sensed no danger lurking nearby.

In contrast, the flight instructor was standing there with her hazel eyes wide and her mouth hanging open, looking as though she was about to keel over.

Linc followed her line of sight to the base of the roll-up door. The concrete was spotless.

No dust.

No blood stain.

And no body.

Zoe took a shaky breath. “That’s impossible!” She wanted to explain what had happened but couldn’t. She had seen the shooting with her own eyes. Had watched the victim fall and bleed. So where had the injured woman gone?

Her companion reached for his mic. “Colson here. False alarm at the warehouse.”

Watching his expression removed all doubt that he blamed her for the false alarm. Only it wasn’t her fault. It hadn’t been. She knew what she’d seen, how she’d felt when the assailant had turned and come toward her. Imagination or hallucination or whatever a person wanted to call it was not enough to scare her that much.

The K-9 handler raised a dark eyebrow. “Well?”

“Oh, no. You’re not going to blame me for this, Colson. I don’t know what really happened, but I am not making anything up. I heard a shot. I saw a victim fall and watched a red stain blossom on her back. There is no way this floor can be this clean and dry after that. Not this fast. There has to be a logical explanation.”

“I’m waiting for it,” he said.

Zoe took a deep breath and exhaled noisily. Slowly shaking her head, she glanced down at the imposing patrol K-9. “I’d rather try to explain it to your dog. She looks more likely to believe me.”

“Don’t let her temporary relaxation fool you. One word or signal from me and Star will be a formidable adversary.”
