Just then the telephone rang and Faber reached for it before we could thank him and say good-night.
"Hello—oh, Miss Tourville, how do you do? Why—er—yes—yes, I'm listening."
They chatted for several minutes, Faber answering mostly in monosyllables. Perhaps it was my imagination, but I thought the conversation, at least at his end of the line, constrained. As he hung up the receiver, I fancied, too, that Faber seemed to look on us with a sort of suspicion. What was his connection with Rita, I wondered? What had Rita told him?
A moment later we had said good-by and had gained the street, Kennedy still making no comment on the case.
"There's nothing more that we can do tonight," remarked Craig, looking at his watch finally as we walked along. "Let us go over to the City Laboratory and see Dr. Leslie, as I promised Blythe."
CHAPTER XX
THE MECHANICAL CONNOISSEUR
Dr. Leslie, the Coroner, was an old friend of ours with whom we had co-operated in several cases. When we reached his office we found Dr. Blythe there already, waiting for us.
"Have you found anything yet?" asked Dr. Blythe with what I felt was just a trace of professional pique at the fact that neither physician had been able to shed any light on the case so far.
