# The House of Mystery explained — The Mystery of 31, New Inn

> Chapter companion for The Mystery of 31, New Inn by R. Austin Freeman.

## 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.

Thorndyke condemns the crime as cruel and unforgivable, vowing to find the culprit.

_Thorndyke expresses his moral outrage and determination._

> I shall make it my very especial business to ascertain whether he is or not. And if he is not, I shall take it to myself as a sacred duty to lay my hand on the man who has compassed his death.

_Thorndyke commits to a personal mission for justice._
