I shot a glance to the guard, who had stumbled to his feet and was grabbing for his gun. He headed out of his station, opening a door that led into the antechamber, presumably to investigate.

"No!" I shouted at him, and threw myself at the security door. I sensed, rather than saw, something else, on the other side of the wall, heading for the exit. I could hear its breath, feel its massive motion through the air, and I hurled my shoulder against the door, slamming it forward, just as something huge and strong thrust a paw through the doorway. The edge of the steel security door slammed forward onto the paw, a member that was neither wholly a paw nor a hand, but somewhere in between, tipped with huge black claws, and drenched in wet, dark, blood. I heard the creature on the far side of the door, only three inches of steel away, snarl in a fury and hatred so pure as to be painful to hear.

Then it started shoving at the door.

The first shove was tentative, but though I strained with all my strength, it still slapped me back a foot across the floor, my boots slipping on the tile. That paw-hand turned, and the talons sank into the steel door in a sudden, snapping motion as the thing took hold of it and started wrenching it back and forth in berserk anger.

"Help me!" I shouted at the guard, struggling to force the door closed. The jailer blinked at me for a second, then flooded with color.

"You!" he said. "My God. What is happening?"

"Help me close this door or we're both dead," I snarled, continuing to push forward with every ounce of strength I could summon. On the far side of the door, the loup-garou gathered its weight and hurled itself against the door again just as the guard rushed forward to help me.

The door exploded inward, throwing me back like a doll, past the guard, who stumbled back through the door that led behind the counter where he'd been sitting and fell to the ground. My upper back hit the barred door that led out into the hallway, eliciting an instant flash of hot agony from my wounded shoulder.

There was a snarl, and then the creature that had been Harley MacFinn came through the doorway. The loup-garou was a wolf, in the same way that a velociraptor is a bird—same basic design, vastly different outcome. It must have been five or five and a half feet tall at the tip of its hunched shoulders. It was wider than a wolf, as though a wolf had been squashed down with an extra five or six hundred pounds of muscle. Its pelt was shaggy, jet-black and matte, except where fresh blood was making it glisten. Its ears were ragged, upright, focused forward. It had a muzzle that was too wide to belong to anything natural, a mouthful of teeth, and MacFinn's blazing eyes done in monochrome grey, the whole stained with blood that looked black beneath the influence of the blending potion. Its limbs were disproportionate, though I couldn't say whether they looked too long or too short—just wrong. Everything about it was wrong, screamed with malice and hate and anger, and it carried a cloak of supernatural power with it that made my teeth hurt and my hair stand on end.

The loup-garou came through the door, swept its monochrome gaze past me, then turned to its left with unholy grace and flung itself at the jailer.

The man got lucky. He looked up and saw the creature as he was regaining his feet, then convulsed in a spastic reaction to the sight of the fanged horror. The reaction threw him a few inches out of the loup-garou's path. He scrambled back, behind the counter and out of my sight.

The loup-garou turned to pursue the jailer behind the counter, slowed because it had to shoulder its way between the counter and the wall, making the counter buckle outward into the room. The jailer got to his feet, gun in hand, took a creditable shooting stance, and emptied the pistol's clip into the loup-garou's skull in the space of maybe three seconds, filling the little antechamber with the sound of thunder and drowning out the cries of the prisoners in their cells in the hall beyond.

The monster kept coming. The bullets bothered it no more than a fly ramming the forehead of a professional wrestler. It rose up as the guard screamed, "No, no, no, nonononononono!" And then it fell upon him, claws and fangs slashing. The jailer tried to turn, to run where there was no place left to go, and the thing turned its head and sank its jaws into the small of the man's back, releasing a spray of blood. The jailer screamed and grabbed frantically at the console, but the loup-garou shook its head violently from left to right, tore him from the console, and hurled him to the floor behind the counter.

I didn't see the guard die. But I saw the way the blood flew up over the hunched, gnarled shoulders of the loup-garou, to decorate the walls and the ceiling. I felt silently grateful when the bent and warping panes of Plexiglas became obscured with scarlet.

It was sometime right around then, as paralyzing agony seared through my shoulder and terrified prisoners screamed and cried out to God or Allah to save them that I noticed that a new noise had been added to the din. The guard had tipped off the alarm when he had scrambled at the console, and it was hooting enthusiastically. Cops were going to come running, and one of the first was going to be Murphy.

The loup-garou was still savaging the jailer's body, and I hoped for his sake that the man wasn't still alive. My best option would have been to slip into the cell block, close the security door behind me, and hope the creature went out into the building at large. Within the cell block, I would have time to put up a warding barrier, something that would keep the monster from coming through the door or the walls to get at me and the prisoners in there. I could fort up there, wait for morning, and live through the night, almost certainly. It was the smart thing to do. It was the survivable thing to do.

Instead, I turned to my staff, at the other side of the little room, and held forth my hand. "Vento servitas," I hissed, forcing out tightly focused will, and a sudden current of air simultaneously threw my staff to me and slammed shut the door to the cells, giving the trapped prisoners what little protection it offered. I caught the staff in my outstretched hand and turned to the barred gate that held me shut in the antechamber with the loup-garou.

I thrust my staff in between the bars and leaned against it as though to pry the bars apart. Had it been only wood and muscle involved, I might have snapped the ancient ash. But a wizard's staff is a tool that helps him to apply forces, to manipulate them and maneuver them to his will. So I leaned my will and my concentration on the staff at the same time I did my body, and worked on multiplying the force I was applying to the steel bars.

"Forzare," I hissed. "Forzare." The metal began to strain and buckle.

Behind me, the loup-garou started thrashing around. I heard the shattering of Plexiglas and shot it a look over my shoulder. The scant protection offered by the potion collapsed, colors flooding my vision. The black of its muzzle warmed to a scarlet-smeared wash of dark brown, stained with wet scarlet. Its fangs were ivory and crimson. Its eyes became a brilliant shade of green. It cut through the blending potion with the ferocity of its stare, and focused on me with an intensity that sent every instinct in my body screaming that death was here, that it was about to jump down my throat and rip me inside out.

"Forzare!" I shouted, shoving against the staff with every ounce of strength I had. The bars bowed out in the middle, parted to an opening perhaps a foot wide and twice as long. The counter exploded outward as the loup-garou came through it, showering me with debris and minor, painful cuts.

I dove through the opening, heedless of my shoulder, conscious only of the beast closing in behind me. My body sailed through with more grace than I could have managed under less panicked circumstances, almost as though the rush of air moving before the charging creature had helped lift me through. And then something closed on my left foot, and I simply lost all sensation in it.
