The wall lay twenty feet ahead; a narrow support ledge ran along it left and right from the beam. A brief dash to the left on that would take him back to the skylight. Chanced a quick glance around and saw two of the Beagle Boys making good time up the walls. The third was somewhere behind him and to his left. No way Jack was risking a look over his shoulder.

He all but ran the last three steps to the wall and didn’t slow when he reached the ledge. With surer footing now he could move faster. Searched the shadows as he hustled toward the skylight and spotted the third Beagle far down the adjoining wall—just pulling himself up onto the ledge. Jack increased his speed. Had to reach that skylight first.

Didn’t slow when he reached the corner—made the turn at his best speed and kept moving toward the skylight. The Beagle was on the ledge now, moving quickly—almost scampering—toward Jack. Didn’t seem the least bit afraid of the height or of falling. If he got to Jack before Jack reached the skylight…

With a final desperation-fueled burst, Jack came abreast of the skylight and leaped off the ledge. Not a long jump—on the way in he’d been able to hang down and swing over to the wall ledge—but he had to be up and through before the Beagle Boy. Snagged the near edge backhanded and used his momentum to swing his legs up. When his sneakers caught the far edge he levered himself up and rolled out to the side. Soon as his body hit the roof he swiveled and slammed the skylight closed.

A howl of frustration filtered through from below. With nothing but air below the skylight, there was no way to open it from inside without a pole, and Jack hadn’t seen one lying about.

“Sorry, Fido,” he muttered; then he was on his way again.

He hopped the alley to the abandoned building and quickly made his way down to ground level. The street was deserted as Jack beat it to his car. Once in the front seat, locked inside, he allowed himself a moment to catch his breath.

What had he learned tonight? Had it been worth the risk?

Definitely. Monnet was testing a drug and, from the way he was going about it, not a legal one. The way the human guinea pigs reacted to it reminded Jack too much of the preppy rioters the other night for it to be anything but the Berzerk stuff Robert Butler had told him about.

Nadia wasn’t going to be happy to hear that her beloved boss was dabbling with Berzerk. The way she’d spoken of Monnet had led Jack to expect a halo hovering over his scalp. But halos tended to dim when you started poking into someone’s corners.

Was Dragovic involved? Had to be. Even if he was miles away tonight, the whole situation reeked of him.

Just as my clothes reek of pigeon guano. Jack started the engine. Time to get home and—
