London: Greening & Co., 1909.
Hardcover. 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*.
