BATTLEFIELD [5]

As soon as she reached the door, just a little ahead of the others, she tried the handle. Satisfied the door would open, she yelled, 'Xian Mei, cover us! The rest of you – grenades!'

None of them needed any further explanation. As Xian Mei turned and began firing at the few zombies still able-bodied enough to lurch towards them (a quick glance confirmed to Sam that none of the remaining creatures were actually running), he, Logan, Jin, and Yerema were fumbling in their pockets. Sam helped Purna shove the door open, and then as the infected on the other side began to register their presence, the five of them pulled the pins on their second batch of grenades and hurled them into what Kevin had earlier told them was the high-security wing. Purna began firing at the creatures closest to the door while Sam and the others grabbed their remaining grenades and repeated the process. Then Purna and Sam swapped places, Sam keeping the infected back while Purna threw her last grenade.

Once again, it was the first, almost simultaneous round of blasts that slammed the door closed. This time Sam and the others were already moving back in readiness, but that didn't prevent them from being liberally spattered with zombie blood when one of the infected, who had been squeezing himself through the narrow gap between the door and frame, was all but sliced in half lengthways when the first grenade went off. Choking and spluttering, Sam was at least secretly gratified to see that Kevin too had had a liberal dousing. The skinny guy was looking down at his gore-streaked overalls with the appalled expression of a kid at a party whose best friend had just vomited all over his favorite T-shirt. Still wiping the stinking, dripping fluid from his face, Sam said, 'Welcome to the club, buddy.'

For a split-second, which coincided with the second batch of grenades going off in the next room, Kevin looked at him with an expression of pure venom. And then his face abruptly and creepily slipped back into its familiar, slightly secretive smile, and he said, 'I'll look forward to receiving my membership badge.'

With Xian Mei and Logan still picking off zombies behind them, Purna and Sam reopened the door to check what damage the second batch of grenades had wrought. As before, the results were both impressive and appalling. Though some of the infected had survived, most had been torn to pieces, and the room now looked like the aftermath of a train wreck. To add to this impression, the central observation tower had collapsed, which meant that as well as severed limbs and mangled bodies, the floor was strewn with an obstacle course of tangled metal and broken glass.

Purna began to cross the room, picking her way through and over the wreckage, heading for the door Kevin had indicated on his diagram, which stood between two rows of cells on the far wall. As she advanced, she gunned down approaching zombies with ruthless efficiency, and Sam, a few steps behind her, did the same. Just behind Sam came Jin and Yerema, firing their pistols when they needed to, and just behind them, keeping his head low, was Kevin. At the back of the group, Logan and Xian Mei wrestled the door closed to shut out the straggle of approaching zombies left in the previous room. Turning, they found themselves cut off from the rest of the group, as at least two dozen of the infected closed in from all sides. Some of the creatures had been injured in the blast, but most were still able-bodied enough to remain dangerous.
