the several doorways and the exact point at which the portiere was drawn aside from the entrance to the alcove.” “It is wonderful,” I cried, “wonderful!” Then, to his astonishment, perhaps, I asked if there was not a small door of communication between the passageway back of the alcove and the large central hall. “Yes,” he replied. “It opens just beyond the fireplace. Three small steps lead to it.” “I thought so,” I murmured, but more to myself than to him. In my mind I was thinking how a man, if he so wished, could pass from the very heart of this assemblage into the quiet passageway, and so on into the alcove, without attracting very much attention from his fellow guests. I forgot that there was another way of approach even less noticeable that by the small staircase running up beyond the arch directly to the dressing-rooms. That no confusion may arise in any one’s mind in regard to these curious approaches, I subjoin a plan of this portion of the lower floor as it afterward appeared in the leading dailies. “And Mr. Durand?” I stammered, as I followed the inspector back to the room where we had left that gentleman. “You will believe his statement now and look for this second intruder with the guiltily-hanging head and frightened mien?” “Yes,” he replied, stopping me on the threshold of the door and taking my hand kindly in his, “if—(don’t start, my dear; life is full of trouble for young and old, and youth is the best time to face a sad experience) if he is not himself the man you saw staring in frightened horror at his breast. Have you not noticed that he is not dressed in all respects like the other gentlemen present? That, though he has not donned his overcoat, he has put on, somewhat prematurely, one might say, the large silk handkerchief he presumably wears under it? Have you not noticed this, and asked yourself why?” I had noticed it. I had noticed it from the moment I recovered from my fainting fit, but I had not thought it a matter of sufficient interest to ask, even of myself, his reason for thus hiding his shirt-front. Now I could not. My faculties were too confused, my heart too deeply shaken by the suggestion which the inspector’s words conveyed, for me to be conscious of anything but the devouring question as to what I should do if, by my own mistaken zeal, I had succeeded in plunging the man I loved yet deeper into the toils in which he had become enmeshed.
