"What are you-?" Monk began.

"Obstacles," Creed said, yanking more cages open.

Monk nodded, understanding. Nothing like littering their trail with scores of squealing footballs. It should slow the gunman down.

They had almost reached the far end of the vivarium when Monk heard the double doors bang open behind them. A short spatter of gunfire followed, but it quickly ended with a startled bark, followed by the clattering fall of a body to the floor.

Chalk one up for the pigskins.

Monk pushed Andrea to the end of the hall and through another set of double doors. Moments later they were back in a basement hallway.

"Those access points into the maintenance spaces," Monk pressed. "Is there one nearby?"

"The only one I know about for sure is back at Dr. Malloy's lab."

Monk studied the crisscrossing hallways and maze of rooms. He was lost. "Can you get us back there?"

"Yes. It's this way."

Andrea headed off, less shocked, more determined. Monk kept to her side. Creed followed. Monk noted him clutching his upper thigh. His pant leg was damp.

Creed met his gaze and waved him on. "Took a ricochet. Just grazed. Keep going."

They had no choice. After another turn, Monk suddenly recognized the hallway. They'd come full circle back to Dr. Malloy's lab. Confirming this, Monk spotted his briefcase resting in the hall outside the open door.

They headed toward it at a full run.

Down the opposite end of the hall, another gunman appeared with a swirl of his black rain slicker. The open lab door still lay another ten yards away.

Monk kept his arm level and fired at the assailant. "Keep going!" he yelled as Andrea and Creed slowed. "Make for the lab!"

While it might be crazy to run toward a man wielding a machine gun, the room offered the only hope of escape.

Monk fired another two rounds. He was almost out, but the shots kept the assailant off balance. Unfortunately, the brief firefight had not gone unnoticed. Behind them, a new barrage erupted. Another gunman. The attackers were trying to trap them in a crossfire.

But by now, they'd reached the lab.

Andrea and Creed dashed inside. Monk bent down as the whine of a round ripped past the crown of his head. He snatched his abandoned briefcase and rolled sideways into the laboratory.

As soon as he was through, Creed slammed the door behind him.

"Locks automatically," Andrea said, hugging her arms around her chest. She kept well clear of the chair where Dr. Malloy's body was still tied.

Monk gained his feet, holding his pistol in one hand and his Tanner Krolle briefcase in the other. "That maintenance access?"

Andrea turned and pointed toward the ceiling above a lab table. A square panel was marked by an electrical hazard symbol.

Monk turned to Creed. "Get her up there. Keep moving."

"What about you?"

"Don't worry about me. I'll be right behind you. Now move it!"

As Creed lifted Andrea onto the table, Monk dropped to one knee. He needed to buy the others as much time as possible to get away. Monk knew it was vital to get the woman to safety. Dr. Malloy must have told her something, something worth killing her over. Whatever that was, Monk wanted to know.

Creed already had the maintenance hatch open and used both arms to shove Andrea through it.

Sheltering behind the dead body in the chair, Monk snapped his briefcase and let it drop open on the floor. All the while, he kept an eye on the door. Locked or not, he knew the door would offer no more protection than a piece of tissue paper. Especially with the firepower behind these bastards.

And Monk was down to the last two rounds in his pistol. He needed the fresh magazine in his briefcase.

As he reached for the spare, the doorknob exploded into the room, along with a good section of the jamb. The door swung open from the impact.

Monk caught a fluttering glimpse of a black slicker and fired at it. Twice. His pistol slide locked open as he ran out of ammunition.

The gunman spun out of view.

Monk snatched for the new magazine while ejecting the spent one. From the corner of his eye, he spotted an arm wave beyond the doorway. A black metal object the size of a baseball flew into the room.

Oh, crap...

Grenade.

Monk dropped both pistol and spare cartridge. Still on one knee, he lifted his open briefcase, caught the grenade inside, and snapped the case shut between his palms. Standing and swinging his arm around, he underhanded the briefcase back through the open doorway.

Even before it passed the threshold, Monk was moving. He turned, leaped to the tabletop, then bounded straight for the open ceiling hatch. Creed's boots had just vanished ahead of him.

"Go!"

Too late.

The explosion deafened and flashed brilliantly. The blast wave shoved Monk up into the crawl space between floors. He struck some HVAC ductwork with his head and collapsed on top of Creed. They struggled for a bit to untangle themselves. Monk took an elbow to an eye.

Cursing and dazed, Monk waved the others onward. He doubted the gunmen would follow them, but until they were somewhere safe and sound, somewhere with lots of guns, he wasn't going to let his guard down.

They stumbled onward, half deaf, half blind.

As Andrea had said, the maintenance space was equipped with catwalks to assist the work crews. Using the walkways, it didn't take long to climb out of the bowels of the building and into the chaos above. Police had already converged on the place. Squad cars, SWAT vans, and a gathering media circus greeted them in the fields outside the building.

As they stumbled into the open, police surrounded them immediately. Even before Monk could begin to explain, a hand grabbed him, pulled him aside, and showed him a badge.

"Homeland Security," the mountain of a man declared. "Dr. Kokkalis, we have orders from Washington to get you all to safety."

Monk didn't protest. He liked those orders just fine. But as they were led off, he glanced forlornly back at the building.

Kat was going to kill him.

That briefcase was damn expensive.

Chapter 6

October 11, 6:28 A.M.

Fiumicino, Italy

Where was she?

Gray crossed out of the terminal of Rome's main airport and headed toward the taxi queue. Horns blared and tour buses rumbled. Even this early in the morning, the airport was snarled with traffic and congested with travelers coming and going.

Gray kept his phone pressed to his ear as he hustled through the crowds. His way was made easier by the lumbering giant who forged a path ahead of him, like a water buffalo fording a flooded river. Gray followed behind in his bodyguard's wake. Joe Kowalski was not a happy traveler. The former seaman clearly preferred the high seas to commercial air travel. He continued to grouse as they headed toward the taxi line.

"Could those seats have been any tighter?" The hulking man cracked his neck and wore a sour expression. "My knees were practically rubbing my ears. Like that airline wanted to perform a damn prostate exam on me. And I wouldn't have minded that if we'd had one woman stewardess." Kowalski glanced back at Gray. "And that gal with a mustache doesn't count."

"You didn't have to volunteer to come," Gray answered as he waited on hold on the phone.

"Volunteer?" Kowalski scowled. "At time-and-a-half pay? That was like putting a gun against my back. I've got a girlfriend to support."

Gray still failed to understand the relationship between the former seaman and the university professor, but at least she had him showering more frequently. Even the black stubble atop Kowalski's head was trimmed into cleaner lines.
