London: Greening & Co. 1909.
First edition. Slight soiling to the spine, and the corners slightly bumped, a lovely, about fine copy, with no rubbing to the usually well-worn pictorial front board, lacking the rare jacket. A collection of stories featuring the nameless detective who never leaves his room, the precursor to Nero Wolfe. A superb copy of a book generally found very worn. Haycraft-Queen Cornerstone, Queen's Quorum.
