The Dutch Shoe Mystery

The Dutch Shoe Mystery is a novel which was written in 1931 by Ellery Queen. It is the third of the Ellery Queen mysteries. Plot summary An eccentric millionairess is lying in a diabetic coma on a hospital bed in an anteroom of the surgical suite of the Dutch Memorial Hospital, which she founded, awaiting the removal of her gall bladder. When the surgery is about to begin, the patient is found to have been strangled with picture wire. Although the hospital is crowded, it is well guarded, and only a limited number of people had the opportunity to have murdered her, including members of her family and a small number of the medical personnel. The apparent murderer is a member of the surgical staff who was actually seen in the victim's vicinity, but his limp makes him easy to impersonate. Ellery Queen examines a pair of hospital shoes, one of which has a broken lace that has been mended with surgical tape. He performs an extended piece of logical deduction based on the shoe, plus such slight clues as the position of a filing cabinet, and creates a list of necessary characteristics of the murderer that narrows the field of suspects down to a single surprising possibility.
