Unwinding the folds of tissue paper in which the stiletto was wrapped, I scrutinized the weapon very carefully. Hitherto, I had seen only pictures of it, now, I had the article itself in my hand. It was not a natural one for a young woman to hold, a woman whose taste ran more toward healing than inflicting wounds, but I forced myself to forget why the end of its blade was rusty, and looked mainly at the devices which ornamented the handle. I had not been mistaken in them. They belonged to the house of Grey, and to none other. It was a legitimate inquiry I had undertaken. However the matter ended, I should always have these historic devices for my excuse. My plan was to lay this dagger on Mr. Grey’s desk at a moment when he would be sure to see it and I to see him. If he betrayed a guilty knowledge of this fatal steel; if, unconscious of my presence, he showed surprise and apprehension,—then we should know how to proceed; justice would be loosed from constraint and the police feel at liberty to approach him. It was a delicate task, this. I realized how delicate, when I had thrust the stiletto out of sight under my nurse’s apron and started to cross the hall. Should I find the library clear? Would the opportunity be given me to approach his desk, or should I have to carry this guilty witness of a world-famous crime on into Miss Grey’s room, and with its unholy outline pressing a semblance of itself upon my breast, sit at that innocent pillow, meet those innocent eyes, and answer the gentle inquiries which now and then fell from the sweetest lips I have ever seen smile into the face of a lonely, preoccupied stranger? The arrangement of the rooms was such as made it necessary for me to pass through this sitting-room in order to reach my patient’s bedroom.
