War time Tangier, policed by Franco's Guardia Civil, thick with many nationalities including Germans and Allies, bitter with the insults of Colonialism, is a dangerous place. Archaeologist Lily Sampson, recruited from her studies in Chicago by the enigmatic Dr. Drury, finds herself in Morocco digging up Neanderthal artifacts at the Cave of Hercules. Quite soon, she's summoned to help the American Legation with an undercover mission linked to Operation Torch. The target date: November 8, 1942. The mission: to control French Morocco, Algeria, and Tunisia, squash Rommel, and thrust into Europe's underbelly. Out in the Atlantic, General Eisenhower will rely on relayed communications. But Lily's mastery of code is interrupted by murder—not one, but two—which not only imperils her, but Operation Torch itself.
