In October 1942, Odette Sansom, a housewife turned British spy, was holed up on Gibraltar waiting for passage to Nazi-occupied France to begin her mission. She had left her three daughters at a convent school in England, a decision so painful, she later said, that it paled in comparison to Nazi torture. She had endured training, learning to shoot, detonate explosives, encode messages and navigate by compass at night. She had tried and failed four times to get to France. At last she was just a boat ride away, but the Polish seaman charged with taking her refused.
