古い邸宅に設定されたwhodunnitミステリーを教えてください。私は4人の容疑者との物語が欲しいです、そして、容疑者ごとに動機とアリバイを知る必要があります。さらに、探偵が各容疑者を除外し、殺人者を特定できた方法も知りたいです
Can you tell me a whodunnit mystery set in an old manor. I want a story with four suspects, and for each suspect I need to know the motive and the alibi. In addition I would like to know also how the detective was able to exclude each suspect and identify the killer
