This is the story of the real bodyguard, Lee Sansum, ex-Royal Military Policeman, martial arts champion, and expert in close protection. Part of Mohamed and Dodi Al-Fayed's protection team, Lee had to guard the most famous woman in the world, Princess Diana. He formed a close bond with Diana and the young princes, particularly Harry, and it was only by a stroke of luck that he was not in the car the night Diana died. That night proved to be the turning point in his own life.

Over the course of his career, Lee has worked with the rich and famous, such as Hollywood stars Tom & Nicole, Pele and Sylvester Stallone, and he gives a candid account of what it's like to work in a job where lives are literally at stake.

Growing up in a tough part of Greater Manchester, Lee learnt the hard way that to survive you need to stand up to bullies and be harder than your opponent. A career in the Royal Military Police took him to the "Bandit Country" of South Armagh, where he pulled an AWOL squaddie out of a honey trap moments before an IRA active service unit arrived to kill him. He worked undercover in Northern Ireland and joined the SIB, the Army's own internal affairs unit, before entering the world of private security, operating in the world's hotspots, such as Libya and the breakaway state of Somaliland.

Lee's story is one of quiet strength, of how reading a situation is invaluable to getting out of trouble. It is one of achieving personal goals and overcoming trauma through the help of his wife, Kate, and through his love of martial arts. It is also a fitting tribute to one of the outstanding figures of our age.
