What is the matter?

There is somebody in the vaults, Masin answered.

I had left my pipe on a stone close to the padlocked door and when you were gone I took a lantern and went down to get it. When I came near the door I was sure I heard some one trying it gently from the other side. I stopped to listen and I distinctly heard footsteps going away. I ran forward and tried to find a crack, to see if there were a light, but the door is swollen with the dampness and fits tightly. Besides, by the time I had reached it the person inside must have got well away.

What time was it?
human
You went out at nine o'clock, sir. It could not have been more than half an hour later.
gpt
Light both lanterns. We must go down at once. See that there is plenty of oil in them.

You had better take your revolver, sir,

I have had that revolver since I was eighteen, he said,
