After a CIA-sponsored op in the Khorasan Valley, operative John Stratton is looking forward to a holiday - until old friend and ex-SBS commander Berry Chandos calls him up out of the blue.

Through his contacts, Chandos has discovered that a nuclear dirty bomb has gone missing in Pakistan. When Chandos disappears a few days later, Stratton finds himself drawn into a desperate race to find his old partner before an assassin targets him and before the bomb can fall into the wrong hands.

Alone and unsupported, Stratton must fight to find his friend and discover the truth in this high-voltage thriller from bestselling ex-SBS operative Duncan Falconer.
