“Yes, sir. Every one who comes in has to pass the switchboard.”

“What time did she arrive?”

“It couldn’t have been more than a few minutes after eleven.”

“Was she alone?”

“No, sir. There was a gentleman with her.”

“Do you know who he was?”

“I don’t know his name, sir. But I have seen him several times before when he has called on Miss Odell.”

“You could describe him, I suppose.”

“Yes, sir. He’s tall and clean-shaven except for a very short gray moustache, and is about forty-five, I should say. He looks—if you understand me, sir—like a man of wealth and position.”

Markham nodded. “And now, tell me: did he accompany Miss Odell into her apartment, or did he go immediately away?”
