Collins sons & co ltd, [1929]. - In-12, Bradel-style black cloth boards, framed in red fillet, title and author's name in red on front board, smooth spine (publisher's binding). "First edition of this detective novel by Agatha Christie (1890-1976), known in France as "Les Sept Cadrans" (The Seven Dials) and later adapted into a series by Chris Chibnall. "This is only the second novel Agatha Christie has written after her divorce from her first husband, Archie, and she said: 'I was gaining confidence in my writing. I felt I would have no difficulty in producing a book a year, and perhaps a few short stories too." She found the "light thriller" type novels easy to write, as they didn't require too much plot or planning, unlike her previous book, "The Mystery of the Blue Train". With "The Mystery of the Seven Dials", Christie has returned to her early writing and resurrected the popular Lady "Bundle" Brent and her accomplices from The Secret of the Chimneys" ("The Home of Agatha Christie" site). Copy complete with publisher's catalog at end. Some soiling and minor tears to boards. Mottling on the edge of the endpapers."
