鍵が中に残された密室の4階の部屋。窓は内側から鍵が掛かかり、煙突は猫でさえ通れないほどの狭さ。ここから犯人はどうやって抜け出したのか?近所の住人が階段で聞いた二つの恐ろしい声の正体は?パリの住人たちはこの謎に対する答えを見出せないでいた。優れた頭脳を持つ者しか気づかないであろうこの事件の謎を、類まれなる洞察力を持つアウグスト・デュピンは解決できるのか?
The room was on the fourth floor, and the door was locked - with the key on the inside. The windows were closed and fastened - on the inside. The chimney was too narrow for a cat to get through. So how did the murderer escape? And whose were the two angry voices heard by the neighbours as they ran up the stairs? Nobody in Paris could find any answers to this mystery. Except Auguste Dupin, who could see further and think more clearly than other people. The answers to the mystery were all there, but only a clever man could see them.
