His cell was tiny, barely big enough for him to stretch fully across its freezing floor. The walls were unadorned cinder blocks, and the door was solid metal, with a slot at the bottom for food and another at eye level for observation.

He was locked down in solitary.

Perfect, he thought.

He was still fully shackled, and in the confusion the guards hadn’t realized that he still sported the transport manacles he’d had on at his arrival.

Perfect, he grinned.

Also in their anger and their desire to see the prisoner punished, the guards hadn’t performed the customary full body search, otherwise they would have taken away his prosthetic leg.

Perfect. He knew he was home free.

Juan Cabrillo had busted out of more than one prison in his life, but this was the first time he’d ever busted into one.

The whole purpose of the fight had been to get himself thrown into solitary as soon as he arrived. Marko and his goon buddy had made perfect targets, but if necessary Cabrillo would have taken on the guards just as easily. None of them here were upstanding citizens doing a needed but dismal job. They were handpicked thugs who were pretty much part of a private army commanded by Pytor Kenin, a fleet admiral and perhaps the second-most-corrupt man on the planet. Cabrillo’s whole plan was to bypass the prison indoctrination process entirely.

He touched the spot where he’d been hit with the shackles. The bleeding had mostly stopped. He looked down at his chest. The tattoos did look real, even though they had been applied in four-hour-long sessions over the past week aboard the Oregon. Kevin Nixon, a former Hollywood special effects artist who’d painted on the special ink, had warned him that it would begin to fade quickly. Hence Cabrillo’s desire to get himself tossed into solitary as soon as he arrived at the prison.

Juan rolled up his pant leg and checked the artificial limb that attached just below his knee. It was neither the most realistic of his collection of prosthetics nor even the most functional. This one was special built for this mission to allow him to smuggle in as much equipment as possible. The leg was almost a perfect cylinder, with only a slight indentation for an ankle. Had a guard slapped on the shackles, he would have been suspicious right away, but the driver who’d done the cuffing was on Cabrillo’s payroll for this mission. Throughout the entire incident, only he had manacled Cabrillo’s legs, as they had planned and choreographed over and over.

Juan fingered his bloody temple and wished they’d rehearsed that bit a little more.

Not knowing the prison’s routine, he decided it best to wait for a while before making his move. It would also allow him some time to recover from the beating. The first part of the operation, hijacking the truck carrying the real Ivan Karnov, had gone off without a hitch. The two drivers and their prisoner were trussed up in an abandoned house at a largely forgotten port town that was the closest to the prison.

When this op was over, a call would be placed to the village’s authorities, and Karnov would once again be headed to whatever fate awaited him here.

The second part, getting smuggled into the prison, had gone as well as to be expected. It was the third phase that gave Cabrillo pause. Max Hanley, Cabrillo’s closest friend, second-in-command of their 550-foot freighter Oregon, and all-around curmudgeon, would call it insane.

But that’s what Juan Cabrillo and his team did on a routine basis — pull off the impossible for the right reasons. And the right price.

And while this mission had a personal component for Cabrillo, he wasn’t above accepting the rest of the twenty-five million dollars they’d been guaranteed.

Over the next thirty-six, frigid hours, Cabrillo figured out the routine for solitary confinement. There wasn’t much to it.

At what he guessed was near noon, the slit at the base of his door was opened and a metal tray with thin gruel and a hunk of black bread the size and consistency of a hand grenade was passed through. He had as much time to eat as it took the jailor to feed the other prisoners on this level and empty the slop buckets the men passed out to him. Judging by the sounds of the guard doing this dreary work, there were six others in solitary. None of the prisoners spoke, which told Cabrillo that if he tried, there would be reprisals.

He remained silent, ignoring the food, and waited. A hairy hand reached back for the tray. The guard muttered, “Suit yourself. The food ain’t gonna get any better,” and the slot slid closed.

Knowing now that no one checked on the men down here other than the once-a-day feeding, Cabrillo set to work. After removing his artificial leg and opening its removable cover, he carefully set his equipment around him. He first used a key to unshackle himself from the irons. The key was a duplicate made from the original the driver carried. Not clanking around like the ghost of Jacob Marley was a relief unto itself. Putting on the shirt and jacket that had been dumped into the cell with him was sublime. Next from the leg came nearly a dozen tubes of a putty-like substance — the key to the whole operation. If this didn’t work as advertised, if Mark Murphy and Eric Stone, Cabrillo’s crackerjack researchers, had messed up, this would be the shortest prison break in history.

He strapped his leg in place and uncapped one of the tubes and applied a thin bead of the gel to the mortar seam between two of the cinder blocks nearest the floor.

All manner of horrible thoughts flashed through Cabrillo’s mind when the gel didn’t react as it had when they were experimenting back on the Oregon. But the brain can think up scary scenarios in fractions of seconds. The chemical reaction was a tad slower.

Stone and Murph had deduced the chemical makeup of the mortar used here by reading through thousands of pages of declassified documents in Archangel, where the company that had built the facility back in the ’70s was located. (In truth, a team from the Oregon had broken into the facility and scanned the documents over a three-night period and fed them into the ship’s mainframe computer for translation, and then Eric and Mark had gotten to work.)

In less than a minute, the acidic putty had completely broken down the mortar. Cabrillo then attached a probe to the tube, so he could stick it into the narrow slit he’d created, and applied more gel to etch away the remaining mortar on the far side of the block. When he was certain it was clear, he kicked the block into a narrow crawl space between his cell’s wall and the prison’s exterior basement wall. He peered into the gloomy space and saw that the next obstacle was a preformed slab of concrete resting on poured-cement footings. Each section probably weighed ten or so tons.

The mortar acid wouldn’t work on it, but the pack of C-4 plastic explosives would more than do the job.

It took Cabrillo nearly an hour to enlarge his one-block hole into an aperture he could crawl through. On the off chance of a random inspection through the peephole, he stacked the blocks in front of it with just enough room to squeeze behind. In the cell’s dismal lighting it would give the optical illusion of a solid wall.

Next, he attacked the wall next to the cell door. Rather than use the acidic putty to remove individual blocks, he first eroded all the mortar he could reach in an area just wider than his body. Again, this was a precaution in case a guard or the warden came around. Only when he was ready to make his move would he blow through the rest of the mortar.

The second-to-last item in his prosthetic limb had been a tiny transmitter. Once he hit the button and its burst signal was sent to the men waiting on the ship, he had six minutes to get the man he had come here to rescue, blow the C-4 he’d already planted, and make it up to the surface.
