I went back to the room, and taking a lamp, tried all the doors.

They were all locked, as I had expected, and the locks were comparatively new.
But I went down the stone stairs to the hall where I had entered originally.

I found I could pull back the bolts easily enough and unhook the great chains.

But the door was locked, and the key was gone! That key must be in the Count's room.

I must watch should his door be unlocked, so that I may get it and escape.
