Days before the Pearl Harbor attack plunges the U.S. into World War II, private eye Maggie Sullivan is hired to find a missing engineer in Dayton, Ohio. Has Gil Tremain been kidnapped, or has he turned traitor — to his employer and maybe his country?
As Maggie pieces together his last movements, she finds there are secrets the man’s ex-wife and his employers don’t want uncovered. Maggie herself is attacked and an innocent witness is murdered. The ruthlessness of her opponent — or opponents — becomes even clearer when there’s an attempt to abduct Tremain’s young daughter. Still more chilling, Maggie’s investigation suddenly attracts the attention of a local crime kingpin.
The attack on Pearl Harbor presses every cop in the city into service protecting manufacturing and research facilities. Stunned by the knowledge their nation will soon be at war, even fearful the mainland itself will be bombed, people cling to family and friends. Schedules and routines shatter. Amid the disruption, alone and aware she can’t count on help from the police, Maggie races to save a man who has now become a liability to his captors.
