“Yeah. Johnny Scaluck was drilled in one of two phone booths that stand right adjoining. He got it through the glass, while he was gabbing. Waiters rushed to the booth but the gunman ducked through a fire door. Nobody remembered seeing him. But after the commotion was over, Herb hustled over to quiz around for the Prosecutor’s office. He found Miss Millett had been in the next booth only a few seconds before Johnny got his. She’d seen the murderer but had been too scared to say so ’til Herb dragged it out of her.”

“How’d she happen to be in a dive like the Blue Blazer, anyway?” That wasn’t the question I really wanted an answer to: What if this killer was still roaming our corridors?

“Lanerd was with her. They didn’t want to go to the class joints, afraid she’d be recognized.” Hacklin tongued the unlighted cigar around. “After she identified this chopper, ordinarily we’d have turned her over to the police, protective custody. But the Prosecutor didn’t want any more mortalities among his witnesses. Johnny the Grocer’d been dropped because he was going to incriminate some high-placed cops. So we didn’t even tell the Centre Street people about her, or let on she’d seen the murderer.”

“You didn’t even tell the security office.” No matter what he thought, that had been dumb.

He didn’t bother to answer. “We had a conference with Lanerd and her agent. They told us Miss Millet was under ironclad contract to appear on this Stack O’ Jack show until somebody guessed her identity. They were ready to tear the Criminal Courts building down, brick by brick, if we tried to keep her from appearing on the show.”

“This killer—” I realized why Lanerd had found that gun so comfortable, nestling in his pocket — “this murderer knew she’d seen him at the time of the shooting?”

“Sure. He warned her to keep her mouth shut or he’d get her, later.”

“Then, supposedly, he’d tell his friends on the Confidential Squad about her, wouldn’t he?”

“He might.” Hacklin spat out a shred of leaf. “Or he might not. He wouldn’t know she’d picked his picture out of the Gallery. ’Course we don’t know for positive any of the force was connected with Scaluck’s wipe-out. But the idea was not to take any chances. That’s why I don’t go for your talking to this lieutenant pal of yours.”

“So you let Tildy Millett stay here. Knowing her being here put other people in danger.” I was beginning to stew about what a killer like that would do if he was cornered in a hotel.
