As an 18-year-old, John Urwin was posted to Cyprus, where he was recruited into a top-secret unit called the Sixteen, whose task was to assassinate key figures throughout the Middle East.
Now he breaks his silence to tell their story. Their training was said to have surpassed that of the SAS in unarmed combat and weaponry.
His description of their four key missions is explosive and a riveting account of the turbulent 1950s in the Middle East.
The Cold War was approaching its height and when there was a mission to be undertaken that no government could be seen to endorse, the Sixteen would do the job.
No previous depiction of a military group, in book or movie, has remotely compared to the secrecy, skills and sheer professionalism of the Sixteen.
