The Mousetrap.

SYNOPSIS Mollie and Giles Ralston are opening their guesthouse, Monkswell Manor, for its first guests. They are new to the business and struggle with the details and an unusually heavy snowstorm. They hear on the radio that a Mrs. Maureen Lyon has been murdered in London and the suspect is wearing a dark overcoat, light scarf, and soft felt hat. Giles is wearing similar outerwear, as are many of the guests. After all the guests have settled in, Mollie receives a phone call from the police station. She is informed that Sergeant Trotter will be coming to the Manor and everyone must fully cooperate with him. The Sergeant arrives on skis, informing everyone that a notebook was found at the London crime scene, listing the address at which the murder occurred and also that of Monkswell Manor, implying that the guesthouse could be the site of a second murder.
