Build a movie plot around this: who deduces that the archaeologist is actually the field marshal? Bramble
June 1942. Corporal John Bramble (Franchot Tone) is the sole survivor of a British tank crew after a major battle with Erwin Rommel's victorious Afrika Korps at the Battle of Gazala. Delirious, he stumbles across the North African desert into the Empress of Britain, a small, isolated hotel owned by Farid (Akim Tamiroff). The staff consists of just Frenchwoman Mouche (Anne Baxter), as the cook has fled and the waiter Davos was killed the night before by German bombing.Before Farid and Mouche can decide what to do with the newcomer, the swiftly advancing Germans take over the hotel to use as headquarters for Field Marshal Rommel (Erich von Stroheim) and his staff. Bramble assumes the identity of Davos to save himself. When Rommel summons him to a private chat, Bramble is stunned to discover that Davos was a valued German spy, but manages to play along. He learns that he is to be sent to Cairo next.Later, he steals a pistol from genial, music-loving Italian General Sebastiano (Fortunio Bonanova), planning to serve the field marshal a bullet rather than coffee the next morning. Not wanting trouble, Mouche steals the pistol and waits on Rommel herself. When some captured British officers are brought to the hotel for a luncheon with Rommel, one of them (a past guest) realizes that Davos has been replaced. Bramble privately explains who he is and what he plans to do. The officer orders him to use his position of trust to instead gather military intelligence.At the luncheon, Rommel teases his guests, allowing them to ask him twenty questions about his future plans. Bramble listens with interest. From the conversation and later remarks by Rommel, he eventually deduces that the field marshal, disguised as an archeologist before the war, had secretly prepared five hidden supply dumps, the "Five Graves to Cairo", for the conquest of Egypt. The final piece of the puzzle (their locations) falls into place when Bramble realizes that Rommel's cryptic references to points Y, P, and T refer to the letters of the word "Egypt"...
