Farewell Valhalla — Mike Whicker

Evansville, Indiana. 1949. Erika Lehmann returns to the southern Indiana town where in 1943 she infiltrated the wartime Naval shipyard as a German spy. Now she is sent back there by the CIA on what should be an easy covert mission to find certain records. That assignment is cut short as she finds herself embroiled in an unexpected and harrowing rescue mission that forces her to reveal her true identity.
