He yawned widely, then twisted his wide mouth in a grim grin. There had been a time, he reminded himself disgustedly, when an hour or so of sleep was enough. Especially when he was working on a case. But he was getting older. Besides, this wasn’t his case. Not officially. Thus far there wasn’t a fee involved, but from what Marie Leonard had told him about Bert Jackson’s phone call from her apartment he felt pretty certain he’d receive an offer before long. Whoever had gone so far as to murder an elevator operator and ransack his office and apartment must be convinced that the data for Jackson’s graft story was in his possession. It wasn’t difficult, now, to surmise approximately what must have happened after Jackson left the Las Felice at ten o’clock. He probably stopped some place to call Mr. Big back and foolishly made a date to meet him that night, trusting that his story about a detective named Shayne having possession of the material would hold as life insurance for him.
