For I believe Herbert took at first only a casual glance at the room, and then immediately got down on his stomach and wriggled under the bed. The chest had not been replaced, and with his searchlight he examined every inch of the under-side of the bed, including the box mattress. All this was in silence, with the Inspector watching him and half-amused. As I have said before, Mrs. Lancaster’s bed stood with its head toward her husband’s room behind it, and she had been found lying on the side toward the door into the hall. This was her customary place in it. Beyond the closet door stood a small chest of drawers, and it was to this corner, between the bed and the door to the hall, that Herbert Dean practically confined his activities that night. From the bed he moved to the bed table beside it and followed much the same procedure there. The chest of drawers he examined, not only from beneath, but by pulling out each drawer and minutely inspecting its edges. And at last he took down a picture or two from the wall.
