The Castle of Sin

[1949]. 240pp. Green publisher's cloth boards (rubbed and rounded on corners and spine ends, lightly worn, slightly cocked). Lending sheet on front free endpaper, else no other library markings. Internally a few marks on well-thumbed pages, but strong and sound. In its original, vintage dust jacket (rubbed and scuffed, a few spots, rubbed at edges, misaligned, interior tape reinforcements over short tear). Dust jacket fitted with archival-quality mylar wrapper to protect & prolong its life. It is not adhered to the book or to the jacket. A hard to find, fast-moving thriller from the author of The Mark of the Leech. The fourth Chief Inspector Flagg novel.
