When Edgar Q. Bartholomew is handed a letter and key meant for someone else entirely, a simple case of mistaken identity spirals into something far darker in this 1923 masterpiece from the woman who invented the detective novel. A stranger in a hurry, a lawyer's careless mistake, and suddenly our Edgar holds secrets that belong to another man who shares his name. But there are three Edgars in this tale, and as the layers of deception peel back, the question becomes not who Edgar is, but which of the three he truly is. Anna Katharine Green, the Victorian genius behind "The Leavenworth Case," constructs her puzzles with the precision of an architect, and "The Step on the Stair" reveals family inheritances, hidden relationships, and identities so cleverly swapped that the truth seems to shift with each revelation. The courtroom floor plan in the frontispiece hints at the dramatic reckoning to come, where identities must be unmasked and love itself becomes the final prize. This is Golden Age mystery at its finest: intricate, deceptive, and utterly irresistible.
