The courage of women dropped into Nazi-occupied Europe in order to work for Special Operations Executive (SOE), was immense. Thirty-nine entered occupied France in this way, mostly by parachute. Boyd’s recommendation of this debut novel by Lori Inglis Hall was what attracted me to it. Tessa and Theo are twins who have grown up in a comfortable home in Cambridge with an English lecturer father and a French mother. In fact, she is putting her life in constant danger, working for SOE in occupied France.
