Mike Walker adapts C S Forester's gripping guerrilla warfare story set in Napoleonic Spain.
Made famous by Hollywood as The Pride and the Passion.
Partisan groups under charismatic leaders wage a desperate war in which no quarter is given by either side.
The hero of The Gun is the gun itself, a massive 18 pounder that is dragged across the mountains and plains of Spain - an epic task.
Throughout the story, the gun changes the lives of those who fight each other to the death in order to gain control of it.
The Gun is a companion piece to The Gun Goes to Hollywood, which tells the story behind the Hollywood version, which was directed by Stanley Kramer and starred Cary Grant, Frank Sinatra and Sophia Loren.
C S Forester was famous for his tales of adventure and military crusades, most notably the Hornblower series.
Mike Walker has written innumerable radio plays, and won a clutch of awards, including a Sony, BAFTA and Writers Guild Award.
His recent radio includes Our Mutual Friend for BBC Radio 4.
