The Three Coffins

Dr. Gideon Fell investigates an impossible murder in 1930s London. A man is shot inside a study where the doors and windows were locked from the inside, with footprints in the snow outside showing no one approached or left the room. The investigation becomes more complex when a second seemingly impossible murder occurs - this time with a victim found dead in the middle of an unbroken stretch of snow-covered street. Both crimes connect to an old legend about a vampire and three coffins. The novel features what became known as Fell's "Locked Room Lecture," a famous chapter where the detective outlines and analyzes the various ways impossible crimes can be executed in detective fiction. This meta-discussion occurs naturally within the story while providing insight into the locked room mystery subgenre. The book stands as a prime example of Golden Age detective fiction's focus on elaborate puzzle plots and fair-play mysteries. Its exploration of the boundary between the seemingly supernatural and the rationally explainable remains a central theme throughout the work.
