Why did the American ambassador Mr. Otis purchase the Canterville Castle, although people told him it was haunted?
Mr. Otis, an American ambassador, purchases Canterville Castle, even though everyone tells him that it is haunted. His reasoning is that the United States has everything that money can buy, and if there really were ghosts in Europe, there would surely be one in a museum in America. The family takes a very commonsensical approach to the presence of a ghost. When Mrs. Otis finds a blood stain in her living room, the housekeeper tells her it's the blood of Lady Eleanore de Canterville, whose husband, Sir Simon de Canterville, killed his wife in 1575. The eldest son, Washington, immediately applies stain remover to the spot, but when the blood stain disappears, there is a flash of lightning and a clap of thunder. The next night, Mr. Otis sees the ghost and offers it some lubricator to make its chains less noisy.
