“I suppose so.” Wolfe opened his eyes a little. “That would naturally occur to you. On the telephone you mentioned his visit to me. Do you know what its purpose was?”

“I know all about it. It was through my Mend Sarah Barstow that I heard of you. I persuaded my uncle to come to see you. I know what he told you and what you said to him. I told my uncle he was a sentimental romantic. He was.” She stopped, and kept her lips closed a moment to get them firm again; I looked up to see it. “I’m not. I’m hard-boiled. I think my uncle has been murdered, and the man who killed him is Paul Chapin, the writer. I came here to tell you that.”

So here was the notion Wolfe had entertained, coming right to his office and sitting on a chair. But too late? The five hundred a week had gone out to get some air.

Wolfe said, “Quite likely. Thank you for coming. But it might be possible, and more to the point, to engage the attention of the police and the District Attorney.”

She nodded. “You are like Sarah Barstow described you. The police have been engaged since Wednesday noon. They have been willing so far, at the request of the president of the university, to keep the matter quiet. There has been no publicity. But the police — you might as well match me at chess against Capablanca. Mr. Wolfe...” The fingers of her clasped hands, resting on the package on her lap, twisted a closer knot, and her voice tightened. “You don’t know. Paul Chapin has the cunning and subtlety of all the things he mentioned in his first warning, the one he sent after he killed Judge Harrison. He is genuinely evil... all evil, all dangerous... you know he is not a man...”

“There, Miss Hibbard. There now.” Wolfe sighed. “Surely he is a man, by definition. Did he indeed kill a judge? In that instance the presumption is of course in his favor. But you mentioned the first warning. Do you by any chance have a copy of it?”

She nodded. “I have.” She indicated the package. “I have all the warnings, including...” She swallowed. “… the last one. Dr. Burton gave me his.”

“The one after the apparent suicide.”

“No. The one... another one came this morning to them. I suppose to all of them; after Dr. Burton told me I telephoned two or three. You see, my uncle has disappeared... you see...”

“I see. Indeed. Dangerous. For Mr. Chapin, I mean. Any kind of a rut is dangerous in his sort of enterprise. So you have all the warnings. With you? In that package?”
