In The House Without a Key we are introduced to Chan, a corpulent father of nine, as he uses all his considerable faculties to solve the mystifying case of a murdered father and a missing jewel box. When John Winterslip is sent to Hawaii to retrieve his elderly Aunt Minerva, he fully expects to return home quickly. His Boston Brahmin roots, his successful investment business, and his family-approved fiancée are all luring him back home. Shortly after his arrival in Honolulu, however, his uncle, who was reputed to have consorted with pirates, is murdered. Detective Charlie Chan takes up the case.

本作は名探偵チャーリー・チャンの初登場作であり、単なるミステリーを超えた「文化の衝突」を描く傑作です。厳格なボストンの価値観を持つ青年が、楽園ハワイで自己を再発見する過程は文学的にも秀逸。著者の流麗な筆致は、南国の空気感と共に、人間の内面に潜む偏見と真実を鮮やかに暴き出します。 映像化ではチャンの活躍が際立ちますが、原作の白眉は彼の「静かな叡智」が周囲を感化する繊細な心理描写にあります。映像版の視覚的スペクタクルに対し、書籍は当時の社会情勢や人種間の機微をより多層的に伝えてくれます。活字が紡ぐ濃厚な情緒と映像の躍動感。両者を味わうことで、伝説の探偵の真髄に深く触れられるはずです。
