legend or not, you can take my word for it there was a visitor, other than Skeel, in the Odell apartment that night."
"That's all right, too," conceded Heath reluctantly. "But, even so, this other fellow is only valuable to us as a possible source of evidence against Skeel."
"That may be true, Sergeant." Markham frowned perplexedly. "Only, I'd like to know how that side door was unbolted and then rebolted on the inside. We know now that it was open around midnight, and that Mannix and Cleaver both used it."
"You worry so over trifles," said Vance negligently. "The door problem will solve itself once we discover who was keeping company with Skeel in the Canary's gilded cage."
"I should say it boils down to Mannix, Cleaver, and Lindquist. They were the only three at all likely to be present; and if we accept Cleaver's story in its essentials, each of them had an opportunity of getting into the apartment between half past eleven and midnight."
"True. But you have only Cleaver's word that Lindquist was in the neighborhood. And that evidence, uncorroborated, can't be accepted as the lily-white truth."
Heath stirred suddenly and looked at the clock.
