“I think I could give you it clearest if I were sure of one thing first. I believe that's the body of young Hassendean who lived in this house, but I haven't examined it closely—didn't wish to disturb it in any way before you turned up. If it is young Hassendean's body, then I can fit some other things into my evidence. Perhaps you'll have a look for yourselves and see if you can identify him.”

The Inspector exchanged a glance with his superior.

“Just as you please, sir,” he answered.

He crossed the room, knelt beside the chesterfield, and began to search the pockets in the body's clothes. The first two yielded nothing in the way of identification, but from one of the pockets of the evening waistcoat the Inspector fished out a small card.

“Season ticket for the Alhambra,” he reported, after glancing over it. “You're right, doctor. The signature's here: Ronald Hassendean.”

“I was pretty sure of it,” Dr. Ringwood answered. “But I like to be certain.”

The Inspector rose to his feet and came back to the hearthrug.

“Now, perhaps, sir, you'll tell us the story in your own way. Only let's have it clear. I mean, tell us what you saw yourself and let's know when you're bringing anything else in.”

Dr. Ringwood had a clear mind and could put his facts together in proper order. In spite of his physical weariness, he was able to take each incident of the evening in its proper turn and make it fit neatly into its place in his narrative. When he had finished, he had brought the story up to the point when the police arrived. As he closed his tale, the Inspector shut his notebook with a nod of approval.

“There's a lot of useful information there, doctor. We're lucky in having your help. Some of what you've told us would have cost a lot of bother to fish out of different people.”
