The story is about a math student named Malcolm Malcolmson, who is seeking a quiet place to work on his studies. Luckily, after searching for a time, he discovers a long-abandoned home of a judge in the town of Benchurch and takes up residence for a time.
The house is a strange one
it was an old rambling, heavy-built house of the Jacobean style, with heavy gables and windows, unusually small, and set higher than was customary in such houses, and was surrounded with a high brick wall massively built.
However, the student is young and skeptical, so pays no mind to the superstitious warnings; and yet slowly, over the course of the days that he has stayed in the haunted abode, he realizes that the house is infested with rats, which both unsettles and alarms him, as they make quite a racket while he attempts to work on his mathematical quandaries.
Furthermore, he is warned by various characters that the Judge’s house is a haunted one, as the judge was a twisted man who sent many criminals to death by hanging with complete impunity. One day, after traveling to the local inn “The Good Traveler,” Malcolmson meets with local doctor and scholar Dr. Thornhill who tells him about the Judge’s evil deeds. So twisted was this judge, Malcolmson is told, that he had the rope used to hang many of the criminals hung from the warning bell in his home before his death.
