Overview

Ran, Sonoko, Kogoro, and Conan are at a tennis court when they find Tooru Amuro there. Later, Conan has a concussion from a flying racket and rests inside the racket's thrower's villa. Later, a man is killed inside the villa while Conan rests inside it. Conan deduces that it was a locked room murder as the body blocked entryway from the door and the windows were locked from the inside. Three suspects were named as Conan tries to figure out the mystery behind this locked room murder.
