"Then I won't use it. I'll sleep in the guest-room," I added swiftly, lest she leap to feminine conclusions. "You might take him another bowl of water--he's all right with you--and spread the New York Times on the floor--and a damned good use for it--and bring out my clothes and things. He seems to have quite a leech for you and we'll just leave him there to think things over by himself." "How about his food?" she asked. "Shouldn't he have a special diet?" "No. I'll let him go hungry for a day or so. So long as he has plenty of water it won't hurt him. Then when he's weak enough so as not to be dangerous I'll bring him some nice dog-biscuits and warm milk and he'll learn to love me the best way, by the alimentary canal." She looked at me closely, "You _do_ look rocky," she said. "You've had a shock, too. Hadn't I better call the doctor?" I shook my head. "No more doctors, please. I'm out of condition, I guess, and all this dodging Great Danes is hard on the nerves. I'll go down and mix myself a brandy-and-soda. You might join me when you've moved my things upstairs. We've got to talk over a lot of things." When I finally managed to settle down in my den with a stiff drink I felt besieged, bewildered and backed up against the wall. There could be no reasonable doubt about it--_the dog knew_! Ponto knew that I was an interloper, that the real Winnie Tompkins no longer existed, that a stranger was masquerading in his body and clothes. The uncanny instinct of a dog had led him to the truth when even Winnie's wife had been deceived. This was a new twist in the maze. I couldn't imagine the Master of the Rat-Race watching with scientific detachment to see whether Frank Jacklin would make it or would be disqualified in the first round. Of one thing I was certain, unless I could establish some kind of personal understanding with Ponto, suspicion would gather around me. For the moment, Germaine did not doubt that I was her husband: my conduct had puzzled her but she had lived with Winnie so long that it was probable that she no longer specifically noticed him. Virginia Rutherford would be more dangerous--she was a woman scorned and she had been tricked out of an intrigue. She had every motive for digging out or even for inventing the truth, but I had given myself a good excuse to keep her at arm's length. She couldn't force her way into my clubs. I would tell my office staff to keep her away from me, and she couldn't be so ill-bred as to thrust herself into my home. If I could appease Ponto and avoid Virginia, I had a fair chance of getting away with it. "Beg pardon, sir!" It was Myrtle. "Yes, Mary?" "Mrs. Rutherford is back, sir. She wants to see you." "Tell her I am not at home," I replied in a clear carrying tone. "And that I never will be at home to her."
