18 May.--I have been down to look at that room again in daylight, for I must know the truth. When I got to the doorway at the top of the stairs I found it closed. It had been so forcibly driven against the jamb that part of the woodwork was splintered. I could see that the bolt of the lock had not been shot, but the door is fastened from the inside. I fear it was no dream, and must act on this surmise.
