Brute Force — Andy McNab

A cargo ship is apprehended by the authorities off the coast of Spain, packed with enough arms and ammunition to start a war. Twenty years later, an unknown aggressor seems intent on taking out those responsible for the treachery â€" one by one.
The last victim was brutally tortured with a Black & Decker drill and then shot through the head at point-blank range.
And Nick Stone â€" ex-SAS, tough, resourceful, ruthless, highly trained â€" is next on the killer's list. He has only two options â€" fight or flight â€" but which do you choose when you don't know who you are up against?
