"In the running for the best mystery of 2026. With a trove of tropes that mystery lovers will love, it will remind you, in the best way, of Agatha Christie."—Stephen King Arthur Fletch, one of the world's bestselling novelists, is a reclusive genius known for his iconic protagonists and fiendish twists. When six struggling authors are invited to spend a weekend on his private Scottish island, they arrive to discover a shocking secret: Arthur Fletch is dead . . . and his last book is unfinished. Desperate to publish the novel, Fletch's agent and editor have summoned these writers in the hope that one of them will imagine a worthy ending for this final book. To sweeten the deal, they are offering an irresistible prize: in addition to ghost-writing the last chapter––for a mind-boggling sum––they will also help the lucky writer successfully re-launch their own career, guaranteeing future bestsellers. The catch: the writers have just seventy-two hours to finish Fletch's magnum opus. It's the perfect plot. All it needs is a killer ending.
