London, Cassell & Co, 1905. Hardback first edition and first impression. The book is in near fine condition. Some bumping to the spine tips but unfaded. Slight mottling to the lower board. Light rubbing to the illustrated upper board. Owner's name to front pastedown beneath an erased owner's name. Separation to front hinge, though binding still tight. Some light foxing. A scarce book and the author's first solo publication, preceding his famous Dr Thorndyke books.
