"Editor's Note. – Mrs. Futrelle undertook to set up a problem which The Thinking Machine could not solve. 'Wraiths of the Storm', in The Sunday Magazine last week, presented what she thought to be a mystery story impossible of solution. Printer's proofs of the story were submitted to Mr. Futrelle, who, after frequent consultations with Professor Van Dusen – The Thinking Machine – evolved 'The House that Was' as the perfect solution."
