I called Craig and, as I did so, my curiosity got the better of me and I sought out an extension of the wire in a den across the hall from the library, where I could listen in on what was said.
"Hello, O'Connor," answered Craig. "Anything from Burke yet?"
"Yes," came back the welcome news. "I think he has a clue. We found out from here that she received a long distance message during the afternoon. Where did Jameson say you were—Rockledge?—that's the place. Of course we don't know what the message was, but anyhow she went out to meet some one right after that. The time corresponds with what the maid says."
"Anything else?" asked Craig. "Have you found any one who saw her?"
"Yes. I think she went over to your laboratory. But you were out."
"Confound it!" interrupted Craig.
"Some one saw a woman there."
"It wasn't the maid?"
"No, this was earlier—in the afternoon. She left and walked across the campus to the Museum."
"Oh, by the way, any word of Norton?"
