The Collaborator

A friend's death drives an Italian woman to collaborate against her criminal family in this "propulsive, neatly structured thriller" (Guardian (UK)).

She is an Italian accountancy student in London, and her boyfriend Eddie teaches at a language school. But the prime reason Immacolata Borelli came to Britain was to look after her gangster brother, wanted for multiple murders back home in Naples. For the Borelli clan are major players in the Camorra, a crime network more close-knit and ruthless than the Sicilian Mafia.


Mario Castrolami is a senior Carabinieri investigator of the Camorra, his career dedicated to destroying the corruption and violence of the clans. When Immacolata calls from London to say she is prepared to collaborate with justice—to betray her own family—he knows she is setting in motion a terrifying and unpredictable series of events.


The Borellis will not lose their criminal empire without a vicious fight. They will use anything and anyone to prevent her from giving evidence against them. Even Eddie, and Eddie's life.

Praise for The Collaborator
"A dense, intensely satisfying thriller from one of the modern masters of the craft." —Daily Mail (UK)
"No summary can suggest its depth and texture. Seymour is not one to cut corners. He does his research, thinks hard about his story and gives us richly imagined novels that bristle with authenticity. Very few thriller writers tell us as much about their characters." —Patrick Anderson, The Washington Post
"Seymour's twenty-sixth novel builds relentlessly to a fever-pitch conclusion in which a Camorra killer, a hostage rescuer, and a kidnapped victim—characters developed with consummate skill—are all one step from death. Highly recommended for thriller readers." —Library Journal starred review
