Sinister House by Fred M. White — Read

"Now, I want you boys to listen to me carefully," Lyston said. "We are up against a very big thing here, and we shall have to move with extreme caution if we are to succeed in bringing those two scoundrels to justice. I am not going to go into all that Mr. Heronspey told me, because, for the moment, it would be superfluous, and, at the same time, more or less betraying confidence. But I think we can take it for granted now that the proper tenant of number seventeen Manton-street, otherwise known as the Sinister House, is Ian Heronspey's daughter.

And by a natural process of reasoning, Miss Pamela Dacre is the old gentleman's great-granddaughter. For the moment we can ignore the link between the occupant of the Sinister House and Miss Dacre. By that link I mean Miss Dacre's mother. Now Vivian Beaucaire has discovered the family skeleton. He is playing on the intense pride of the old man with a view to obtaining money from him. He has already got two thousand pounds."
