Horrified, the listeners looked at one another in blank dismay. Even Mr. Narkom's usually ruddy countenance had undergone a change as the sound came to his ears. Supernatural or not it acted like a charm, for in another minute the room was cleared and Cleek, Mr. Narkom and the Coroner stood alone.

Mr. Narkom nodded.

"Very. Coming along, Headland?"

"No, not just for a moment or two. I want to look round for myself if you don't mind. Just an odd fancy, don't you know! But don't wait for me, Mr. Narkom. I'll see you later on."
