He was looking out onto an ell of that floor. Onto a tableau of violence. There was just a single office suite on that ell, directly opposite him. On one of its double doors was lettered "Continental Exhibition Corp." The frosted glass of the other door was almost completely broken out, leaving a jagged-fringed aperture through which to view the scene within. Wilson Lamb flattered himself on being pretty cool headed under all circumstances. But he blinked three times rapidly now. Inside the Continental Exhibition Corporation one man was slumped over a desk, an automatic half-gripped in his inert hand. He was very dead. Half his head was shot off. Another man was sprawled on the gray broadloom of the reception room, a brownish puddle beneath his side. He wasn't going to be going any place in a hurry, either. Even as Lamb stared at the carnage, a third figure appeared, wobbling drunkenly from an inner office. He came stooped over, holding his side. Crimson-speckled froth at his lips. He got to the shattered glass panel and moved the lips at Wilson Lamb. "Tell 'em--the police--it was--was Whisper Ross from--from Chi--" He coughed twice on the "Chicago," then caved in on himself and went flat in the hallway. Lamb saw an ashen-face bespectacled man peering around the corner of an ell. From further back, through an open doorway, a girl's voice was shrieking for the police over the phone. Lamb remembered the fact that he had a gun on his person. It might be extremely embarrassing if the police picked him up for questioning. Ducking back through the firedoor, he ran quickly up to the sixteenth floor, up past the fifteenth. Nothing had been heard up there yet. He caught a down car and got out just as the first prowl car came sirening its way into the side street curb. Afterward, outside the police cordon thrown around the building, somebody jostled against him, peered under his hat brim. Later, Lamb recalled the bluish scar crescent on his left cheek. "Hey, aren't you Reynolds of the Dispatch, pal?" "Nope," Lamb said. "You're a reporter with one of the local sheets, aren't you?" the other persisted. "I know I've seen you around before." "You must have been wearing your other glasses, Bud," Lamb said and turned away. Maybe it was the effect of seeing the handiwork of that other unknown killer. For the police had nabbed nobody yet in that mid-town mid-day shooting. Anyway, Lamb had the itch to strike. It was like a thirst building in a guy. You've seen somebody else dip into a tall cool one and after a while you feel like you got to have one yourself. Those three dead men on the thirteenth floor of that office building had acted like an aphrodisiac on Wilson Lamb. He wanted to get him his corpse. But soon.
