Kennedy would say nothing more, and we ate our luncheon in silence.  Fletcher, who had decided to lunch with the Greenes, called Kennedy up on the telephone to tell him it would be all right for him to call on Miss Bond later in the afternoon.

“And I may bring over the apparatus I once described to you to determine just what her nervous condition is?” he asked.  Apparently the answer was yes, for Kennedy hung up the receiver with a satisfied, “Good-bye.”

“Walter, I want you to come along with me this afternoon as my assistant.  Remember I’m now Dr. Kennedy, the nerve specialist, and you are Dr. Jameson, my colleague, and we are to be in consultation on a most important case.”

“Do you think that’s fair?” I asked hotly, “to take that girl off her guard, to insinuate yourself into her confidence as a medical adviser, and worm out of her some kind of fact incriminating someone?  I suppose that’s your plan, and I don’t like the ethics, or rather the lack of ethics, of the thing.”

“Now think a minute, Walter.  Perhaps I am wrong; I don’t know.  Certainly I feel that the end will justify the means.  I have an idea that I can get from Miss Bond the only clue that I need, one that will lead straight to the criminal.  Who knows?  I have a suspicion that the thing I’m going to do is the highest form of your so-called ethics.  If what Fletcher tells us is true that girl is going insane over this thing.  Why should she be so shocked over the death of an uncle she did not live with?  I tell you she knows something about this case that it is necessary for us to know, too.  If she doesn’t tell someone, it will eat her mind out.  I’ll add a dinner to the box of cigars we have already bet on this case that what I’m going to do is for the best—­for her best.”

Again I yielded, for I was coming to have more and more faith in the old Kennedy I had seen made over into a first-class detective, and together we started for the Greenes’, Craig carrying something in one of those long black handbags which physicians use.

Fletcher met us on the driveway.  He seemed to be very much affected, for his face was drawn, and he shifted from one position to another nervously, from which we inferred that Miss Bond was feeling worse.  It was late afternoon, almost verging on twilight, as he led us through the reception-hall and thence onto a long porch overlooking the bay and redolent with honeysuckle.

Miss Bond was half reclining in a wicker chair us we entered.  She started to rise to greet us, but Fletcher gently restrained her, saying, as he introduced us, that he guessed the doctors would pardon any informality from an invalid.
