This concise, fast read tells the true story of a self-made double agent who bluffed his way into the most ambitious Allied deception operation of WWII.

In 1942, German military intelligence believed the Spaniard Juan Pujol Garcia was running a formidable spy network for them inside enemy Britain. In reality their man in London was making it all up, from Portugal.

Pujol had fooled the Germans all on his own after the British embassies in Madrid and Lisbon rejected his services repeatedly. But soon British intelligence would smuggle the dogged double agent to London and build up his subterfuge under the code name Garbo. In 1944, Pujol aka Garbo took the lead on an elaborate Allied deception campaign that fooled Hitler and his generals about the D-Day invasion — and surely saved thousands of lives.

Double-Edged Sword focuses solely on the most crucial moments of an epic double cross that Pujol was so uniquely built to pull off. It equals about 70 print pages in length.
