looked in at her? She was running a finger along the baseboard to see if it was clean! And what's more, I caught her at it once before, in the back hall, when she was pretending to telephone for the station hack." It was that day, I think, that I put fresh candles in all the holders downstairs. I had made a resolution like this,—to renew the candles, and to lock myself in my room and throw the key over the transom to Maggie. If, in the mornings that followed, the candles had been used, it would prove that Martin Sprague was wrong, that even foot-prints could lie, and that some one was investigating the lower floor at night.

But, strangely enough, the fear had left me. I find, as always, that it is difficult to put into words. I did not relish the excursion to the lower floor. I resented
