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.
