“Yes, sir; lor’, where did you find it?”

Sensation. A clue, then, at last! Something had been found which seemed to connect this mysterious murder with the outside world. Instantly the back-door assumed the chief position of interest. The candle found lying in the yard seemed to prove, not only that Hannah had left the house shortly after descending from her room, but had left it by the back-door, which we now remembered was only a few steps from the iron gate opening into the side street. But Thomas, being recalled, repeated his assertion that not only the back-door, but all the lower windows of the house, had been found by him securely locked and bolted at six o’clock that morning. Inevitable conclusion—some one had locked and bolted them after the girl. Who? Alas, that had now become the very serious and momentous question.
