A colleague fell off a cliff mysteriously, gunshots broke out in the secret room, and everyone had an alibi. It was like a perfect crime. The marquis's wife Yumiko is as beautiful as poison, and Takehiko falls into forbidden love. The suspect was shot dead in a closed bedroom, the motive for the murder could not be ascertained, and everyone had a perfect alibi. Can the arrival of Akechi Kogoro bring a turn to the confusing case?
