The doctor bustled away, and Whyland, having made arrangements for the removal of the body, made a very careful examination of the cellar. This done, he sent the constable for the electrician, and asked him to look round and see if he could find anything which had not been there when he left on Saturday.

The man looked about him carefully, and suddenly pointed to the ceiling with an exclamation of astonishment. “Why, there’s the butt of a broken lamp in that holder, sir,” he said. “I didn’t put no lamps in before I left. That’s one of the things I came here to do today.”

“Well, take it out and put in a fresh lamp,” replied Whyland. “I didn’t know the current was on. We’ll be able to see what we’re doing.”
