“What about Stebbins? Could he have been concealed in the house all night?”

“Thorpe could let him in and out, if he wanted to.”

“Into the back part of the house. But Thorpe himself can’t get into the main house, the rooms that we use, after I lock the doors between. Come, now, Professor, you know all that as well as I do. Either you dreamed your ghost, or it’s the real thing, this time. Take your choice.”

“I came the moment I heard you call, at least, as soon as I could slip into a bathrobe.”

“How could you, with no light?”

“I don’t know how I did. It wasn’t exactly luminous, and yet it gave out a very faint glow, enough for me to see it, anyhow. Oh, I shall never forget its awful grin!”
