"You are the very man I want, Bell," he cried. "Sit down; I have a great deal to say to you. There is a mystery of a very grave nature which I hope you may solve for me. It is in connection with a house said to be haunted." He fixed his bright eyes on my face as he spoke. I sat perfectly silent, waiting for him to continue. "In the first place," he resumed, "I must ask you to regard the matter as confidential." "Certainly," I answered. "You know," he went on, "that I have often laughed at your special hobby, but it occurred to me yesterday that the experiences you have lived through may enable you to give me valuable assistance in this difficulty." "I will do my best for you, Edgcombe," I replied. He lay back in his chair, folding his hands. "The case is briefly as follows," he began. "It is connected with the family of the Wentworths. The only son, Archibald, the artist, has just died under most extraordinary circumstances. He was, as you probably know, one of the most promising water-colour painters of the younger school, and his pictures in this year's Academy met with universal praise. He was the heir to the Wentworth estates, and his death has caused a complication of claims from a member of a collateral branch of the family, who, when the present squire dies, is entitled to the money. This man has spent the greater part of his life in Australia, is badly off, and evidently belongs to a rowdy set. He has been to see me two or three times, and I must say frankly that I am not taken with his appearance." "Had he anything to do with the death?" I interrupted.
