From the sound of it, he was gaining. Aiming carefully, he started taking the steps three at a time. Whoever was below him was hitting every one. Now Stone was barely a flight of stairs behind him. At the third-floor level he caught sight of a shadow. The ringing of the steel steps built to a crescendo, echoing off the cinder-block walls of the staircase, sounding much like a modern composition a girl had once dragged him to hear.

The knee was hurting badly now, and Stone tried to think ahead. If the man got out of the stairwell before he could be caught, then he’d have the advantage on level ground, because Stone wouldn’t be able to run him down before the knee went. Stone made a decision; he’d go for a flight at a time.

On the next landing, he took a deep breath and leaped. He landed right, pushed off the wall, and prepared to jump again. One more leap down the stairs, and he’d have his quarry in sight. This time, as he jumped, something went wrong. His toe caught the stamped tread of the steel step—not much, just enough to turn him in midair—and he knew he would land wrong. When he did, his weight was on the bad knee, and he screamed. Completely out of control now, he struck the wall hard, bounced, and fell backward down the next flight of stairs.

As he came to rest hard against the wall, he struggled to get a look down the stairs, but he heard the ground-floor door open, and, a moment later, he heard it slam. He hunched up in the fetal position, holding the knee with both hands, waiting for the pain to subside just enough to allow him to get to his feet. Half a minute passed before he could let go of the knee, grab the railing, and hoist himself up. He recovered his pistol, and, barely letting his left foot touch the floor, lurched into the lobby. The guy was gone, and there was no hope of catching him now. Swearing, he hammered the elevator button with his fist.

He pressed his cheek against the cool stainless steel of the elevator door, whimpering with pain and anger and sucking in deep breaths.

The bust of the century, and he had blown it.

There were only two apartments on the twelfth floor, and the doorman was standing obediently in front of 12-A. The door was open.

“I told you not to open it,” Stone said irritably.

“I didn’t,” the old man said indignantly. “It was wide open. I didn’t go in there, either.”

“Okay, okay. You go on back downstairs. There’ll be a lot of cops here in a few minutes; you tell them where I am.”

“Yessir,” the doorman said and headed for the elevator.
