The House of Fear

Holmes is visited by Mr. Chalmers (Gavin Muir (American actor)), an insurance agent with a strange tale. Seven single men, calling themselves "The Good Comrades", live together in the remote Scottish castle of Drearcliffe House, near the village of Inverneill. Recently one of the "Good Comrades" received a strange message, an envelope containing nothing but seven orange pips. That night, he was murdered and his body horribly mutilated. A few days later, a second envelope was delivered, this time containing six pips, and the recipient also died mysteriously soon afterwards, his battered corpse being recovered from the base of the cliffs. Chalmers holds £100,000 of life insurance policies on the seven men, and suspects that one is systematically murdering the others in order to collect the money, and begs Holmes to investigate.
