Famicom Tantei Club: Kieta Koukeisha (ファミコン探偵倶楽部 消えた後継者 前編? lit. Famicom Detective Club: The Missing Heir) is a text-based adventure game developed and published by Nintendo for the Famicom Disk System. As part of a two-disk series, the first disk (Zenpen) was published on April 27, 1988, while the second disk (Kouhen) was published on June 14, 1988.
Production was directed by Gunpei Yokoi, and the original text was written by Yoshio Sakamoto. The game was one of many mystery-solving adventure games released around the time. Contemporaries include the Misa Yamamura Suspense series and the Jake Hunter series. The primary difference between these games and Tantei Club was the use of a teenage boy as the main character and detective. It became a series in 1989 with the release of the sequel, Famicom Tantei Club Part II: Ushiro ni Tatsu Shoujo.
The game is a standard command-style adventure. The player chooses from a set of text commands to interrogate, examine, or move from place to place. The setting of the secluded mansion gave the game a tense and horror movie-like atmosphere which was well received by fans. The game was ported to the Game Boy Advance in the Famicom Mini series as a single cartridge in 2004, and became available on the Wii Virtual Console in 2007 for 600 Wii points. While the original FDS version requires the player to switch the Disk Cards midway through the game, the GBA and Virtual Console versions can be played without such interruptions. The game was never released outside of Japan.
The story begins with a man named "Amachi" discovering the fallen protagonist on the ground near a cliff. The protagonist discovers that he has lost his memory, and after recuperating, he revisits the cliff and meets a young girl named Ayumi Tachibana. He learns from Ayumi that he is an assistant detective investigating the death of Kiku Ayashiro, and heads over to the nearby Ayashiro estate located in Myoujin village. The Ayashiro family owns a huge plot of land passed down from generation to generation, but there is a strange saying in the village that the dead will return to life to kill anyone who attempts to steal the treasure of the Ayashiro family. As the protagonist investigates the mysterious death of Kiku Ayashiro, he discovers the terrifying connection between this saying and the serial killings which take place.
