What happens
Thorndyke and Jervis visit the house formerly occupied by H. Weiss, now vacant and to let. They inspect the premises, discovering evidence of heavy fastenings on doors and shutters suggesting a prisoner was held. Thorndyke finds a broken pair of spectacles and deduces the room was used for a diabolical crime. The letter-box is empty, indicating Mrs. Schallibaum may have retrieved the letter while they were inside. They separate to avoid being followed.
