What the Mastiff Was Hiding

The impact came before I had time to answer. The surgical-room door shook in its frame, and the crash rolled through the clinic like thunder trapped indoors.

Dr. Aris cried out and stumbled backward. Splinters burst around the deadbolt as Mark drove the tire iron into the other side of the heavy door.

“Give me Brutus!” Mark bellowed. A second strike followed, harder than the first. The pipe wrench I had jammed beneath the handle shrieked against the tile but held.

“You have no chance, Mark!” I yelled. I moved between the entrance, Dr. Aris, and the enormous dog. “Drop that bar and leave before the officers arrive!”

“He belongs to me!” Mark answered. His voice sounded ragged and feverish. “That animal took something that was mine, and I will hurt anyone hiding him!”

The iron punched into the middle panel. Wood flew inward, and a narrow blade of hallway light cut across the floor. One of Mark’s red-rimmed eyes appeared in the opening.

I backed toward the operating table. A man desperate to conceal wrongdoing might run, lie, or burn a house down. Mark was doing something more frightening: he was trying to recover an item.

“What could Brutus have taken?” Dr. Aris asked. Her fingers trembled beside her sides, and her gaze kept darting from me to the ruined doorway.

My thoughts returned to the registration record we had uncovered. Sarah’s message had called Brutus a seizure-alert service dog, then added the strange warning: he held the key.

“Think about the chip,” I told her as another blow rattled the hinges. “Sarah Evans placed that message there for whoever found him. When you examined Brutus, did you check more than his neck?”

“I scanned the usual location,” she said. “Between the shoulder blades. That is where the implant should be.”

Brutus stood beside her, huge and silent. His chest rose slowly, and his eyes remained fixed on the door as if he understood that Mark was coming for something inside him.

I studied the Mastiff’s thick body. “A dog that size can swallow nearly anything. If Sarah knew Mark meant to kill her, she might have used Brutus as a hiding place.”

Dr. Aris stared at me. Then her attention shifted to the radiography table in the center of the room, its metal surface waiting beneath the suspended imaging unit.

“You believe Sarah made him swallow an object?” she asked. Her fear gave way to a sharper expression, the look of a veterinarian solving a dangerous puzzle.

“It could have happened before she vanished,” I said. “Something small enough to go down, but valuable enough for Mark to risk breaking in here.”

Mark hammered the entrance again. The upper hinge pulled away from the wall with a tearing groan. Dust sifted down from the frame.

“Could it remain inside him that long?” I asked. Three years sounded impossible, yet every answer we had found about Sarah had been worse than the last.

“A sizable foreign body can stay in a stomach for years,” Dr. Aris replied. Her training had taken control of her voice. “If it cannot pass into the intestine, it may settle among the gastric folds.”

“Then we find out now.” I pointed toward the table. “Whatever Sarah left behind may be the only proof we have.”

Another blow landed. The door bowed inward, and the deadbolt scraped against its plate. We had minutes at best before the barrier collapsed completely.

Dr. Aris hurried to the controls and powered up the machine. Its motor awakened with a thin electronic whine that seemed painfully small against Mark’s pounding.

“Help me get him onto the platform,” she ordered. “Carefully. We cannot afford to injure him.”

I wrapped both arms around Brutus’s broad middle. He weighed more than three hundred pounds, but he offered no resistance while we lifted his front end onto the cold table.

Dr. Aris raised his hindquarters next. Together, awkwardly and breathlessly, we settled him on his side. His paws shifted once, then went still.

“That’s it,” she murmured. She lowered the imaging head until it hovered over his ribs, then hurried behind the lead-lined shield.

I pressed my arms around Brutus’s neck and felt coarse fur against my face. “Stay with me, big man,” I whispered. “Do not move.”

Mark struck again. The lower hinge surrendered, and the door leaned toward us at a crooked angle. Only the jammed wrench and mangled lock kept it from falling open.

“I am coming through!” Mark shouted. His hand reached through the splintered gap, fingers searching for the latch while the tire iron scraped across the wood.

“Hold him steady!” Dr. Aris called. She touched the exposure control. “The scan is going through.”

The machine clicked. A breath later, the wall monitor changed from darkness to a stark internal picture of Brutus’s body.

His ribs formed a pale sweeping cage around dim lungs and the bright outline of his heart. Beneath them, inside the cloudy shape of the stomach, a rigid form interrupted the natural anatomy.

It was a clean rectangle, too regular to be bone or food. The image showed a dense white object, roughly three inches long and an inch across, buried deep in the stomach.

Dr. Aris pointed at the screen. “There. Near the upper stomach. That is metal.” Her voice broke into a gasp. “It looks like a sealed titanium capsule.”

The answer struck me with brutal clarity. Sarah had not simply disappeared. Before Mark murdered her, she had placed evidence inside the one protector she believed might outlive him.

The message on Brutus’s registration had been a warning disguised as medical information. Sarah had trusted someone to scan him eventually, while knowing Mark would never willingly take the dog to a veterinarian.

A metallic scrape sounded beside me. Mark had forced his arm through the breach, and his hand groped toward the latch. “I can see you!” he shouted.

I turned as he lifted the tire iron and swung without looking. The bar slammed into the pipe-wrench brace. Steel screamed across the floor, the wrench slipped free, and the door swung inward.

Mark dislodged the door brace and gained access to the surgical suite.
