"I seem the only one to have retained my senses," she retorted tartly. "Miss Ward, you were always assuring me I was not very ill, but judging from Doctor Roberts' conduct and my husband's, they must have thought me at the point of death." Nash collected his scattered wits and came forward. "I suppose you will have your way, though the skies fall," he said resignedly. "But I should have thought, my dear, that poor Zybinn's sudden death through imprudent neglect of his health would have warned you to be careful." What rejoinder Mrs. Nash made was lost by Trenholm, who had stood out of sight behind the grandfather clock watching the scene. He waited until, judging from the sounds that came from the other room, they were seated around the dinner table, and then, taking care to make no noise, he ran lightly up the staircase and darted into Mrs. Nash's bedroom. Before going to her supper, Somers had aired the room and remade the bed, and Trenholm's electric torch showed everything in order. First convincing himself that he was the only person in the bedroom, he went over to the wall and taking from his pocket the pen and ink drawing which he had carried away almost under Mrs. Nash's nose, he hung it back in its place. Trenholm laid down his torch on a convenient chair and drew out the thirteenth letter. He had inserted a little paste under the flap before leaving his bungalow, and to all intents and purposes the envelope looked as if it never had been opened. Holding it in his hand, he scanned the bedroom eagerly and spied a dustpan and brush which Somers had carelessly forgotten and left standing by the bureau. Trenholm slipped over to it and laid the envelope on the small pile of trash in the pan. When he had arranged it to his liking, the envelope looked as if it had been brushed up with the rest of the trash, but the Canadian stamps were plainly in view. Trenholm stood up and, taking his torch with him, tiptoed to the hall door which he had left open as he had found it. A glance outside showed that the hall was empty. Looking about the bedroom, Trenholm noticed a screen which Somers had brought into the bedroom and stood between Mrs. Nash and an open window. It would make an excellent hiding place. Like a flash he was behind it. From where he crouched, he had an excellent view of the open door and the entire bedroom. Trenholm drew a long breath--the stage was set, and he had staked all on the fall of the dice! Half an hour passed and he was commencing to worry when a light footfall came down the hall and he heard Betty Carter exclaim at sight of the darkened room.
