Title: End of an Author
Description: When Peter Hanby advertised for a secretary and took her to an isolated cottage in the sea marshes to write his fiftieth novel, he hadn't an idea in his head. Poison, kidnapping, torture, cheating, blackmail, the duchess's diamonds—Hanby had drained them all. They had nothing fresh to offer his spinning brain... But while desperately searching for some new mystery he himself became the mystery that he sought, and it was his secretary who was set the job of solving it.
