This is where it all ends.

Mason Nash was retired. He was a pacifist. He was trying to be a good man.

Then Tartarus came after him – and now he has nothing left to lose.

Tartarus is a private spy agency who have fooled world governments into believing they're benevolent and honourable. Mason Nash knows otherwise.

Framed for Tartarus' misdeeds, Nash and his partners – Eva Destruction and Charles Bishop – are the most wanted ex-spies on the planet. Now they're all that stands between Tartarus and their ultimate victory.

Hunted by every secret service agency around the globe, including their own beloved MI6, the team must prevent a staged terrorist attack without becoming victims themselves.

With the odds stacking up against them and the authorities closing in, Nash must stand alone and face his darkest demons to defeat Tartarus once and for all.

Not everyone will survive.

A non-stop page-turner, Devil's End will keep you guessing until the very end. No reader of Sinclair's novels can miss this thrilling conclusion.
