Everyone knows The Great Escape. Almost nobody knows that one of the Second World War's most audacious prison camp breakouts was actually far more successful.
 
In September 1941, twenty-six British officers tunnelled out of the German POW camp at Biberach, with four ultimately reaching freedom; a success rate more than four times higher than the famous escape from Stalag Luft III. The Lost Tunnel finally brings this forgotten story to light, combining secret tunnelling operations, ingenious deception, forged documents, daring border crossings and a thrilling journey across occupied Europe on the road to freedom.
 
At the heart of the story are remarkable characters such as Michael Duncan and Barry O'Sullivan, whose escape becomes only the first stage of an even greater adventure. For the men who reach Switzerland, liberty is only the beginning of another perilous journey through Vichy France and along escape lines towards safety.
 
This is a gripping tale of ingenuity, endurance and comradeship: a forgotten wartime epic that was, by any measure, one of the most fascinating mass breakouts of the Second World War.
