The House Without a Key
Earl Derr Biggers
 The novel deals with the murder of a former member of Boston society who has lived in Hawaii for a number of years. The main character is the victim's nephew, a straitlaced young Bostonian bond trader, who came to the islands to try to convince his aunt Minerva, whose vacation has extended many months, to return to Boston. The nephew, John Quincy Winterslip, soon falls under the spell of the islands himself, meets an attractive young woman, breaks his engagement to his straitlaced Bostonian fiancee Agatha, and decides as the murder is being solved to move to San Francisco. In the interval, he is introduced to many levels of Hawaiian society and is of some assistance to Detective Charlie Chan in solving the mystery. The novel's denouement is nearly identical to that in the final Perry Mason novel by Erle Stanley Gardner, The Case of the Postponed Murder (1970).
