“Pfui.” Wolfe scowled. “Can any of them get in after hours?”
“No, not unless they have a key — or are let in by someone who has a key. Up to the time of the press showing, even up to yesterday, the first buyers’ show, there were people there every evening in the rush of getting the line ready, but most times there’s no one there after hours. That’s why I picked last night to go to look for that file.”
“There was no one working there last night?”
“No, not a soul.”
“Who has keys?”
“Let’s see.” She concentrated. “I have one. Bernard Daumery.... Polly Zarella.... Ward Roper. That’s — oh no, Mr. Demarest has one. As my uncle’s executor he is in legal control of the half-interest.”
“Who opens up in the morning and locks up at night?”
“Polly Zarella. She has been doing that for years, since before I came there.”
“So there are just five keys?”
“Yes, that’s all.”
