Christmas 1944, in a foxhole in Bastogne, Belgium, the innocent yet charmingly clever protagonist, Corporal Tom Cole, is injured. Wilder moves the action to a romantic wartime London with dimly lit blackout-compliant restaurants and mad dashes to the Tube station at the sound of the air raid sirens where Cole convalesces and falls in love for the first time. But is the mysterious Danish girl he meets at the Shepherdess Cafe on the up and up? Cole is a cellist back home in the States, and Anna says she's a monitor at the War Office, scanning radio waves for incoming German planes. But is she? When Cole goes to the War Office one day to surprise his new lover, she's nowhere to be found. Wilder's story takes Cole on a quest for the woman he loves but no longer trusts, and ultimately parachutes him, a newly minted intelligence officer, behind enemy lines into a concentration camp to save her life and discover the truth.
