# The Sunningdale Mystery explained — Partners in Crime

> Chapter companion for Partners in Crime by Agatha Christie.

## What happens

Tommy and Tuppence, feeling the slump in business, decide to apply their minds to a famous unsolved case: the Sunningdale Mystery. Over lunch at an A.B.C. shop, Tommy recounts the details of the murder of Captain Sessle on the golf links, stabbed with a hat pin. Tuppence immediately points out that the hat pin is anachronistic, suggesting a man committed the crime. Tommy then reconstructs the scene, realizing the 'woman in brown' could have been a man in disguise, using a turf hut to change appearance. They discuss the case's key figures: the wife, Mr. Hollaby, and Doris Evans, the young typist who was with Sessle that night. The chapter ends with Tommy and Tuppence deciding to investigate further, with Tommy planning to visit the golf course and Tuppence to see Mrs. Sessle.
