Karl’s only hope of finding Vahlen lies with a British informant named Brauer, who is being held captive inside Fort Rifugio. After Karl breaks him out of captivity Brauer informs him that enemy officers are meeting at the Siwa Oasis in Western Egypt. On his way to the meeting point Fairburne learns that the officers plan to betray Vahlen to Hitler by giving Hitler Vahlen’s personal diary. Fairburne assassinates the courier and takes the diary for himself. The book details Vahlen’s plans to conquer Europe.
During their next mission Fairburne and Brauer learn of a supertank codenamed the Ratte. Brauer is killed during the mission, and Fairburne joins the LRDG in assaulting the German Controlled Pont du Fahs Airfield. The assault leads to a map giving the location of the Ratte production facility. Fairburne finds the facility where he comes face to face with Valhen. Fairburne manages to destroy the base with the Ratte prototype taking Valhen with it.
