The baker's wife

Late to the bakery one dim, foggy morning, Audrey strikes a vehicle that she can't see even after the collision settles. Emerging from her car into the fog, she discovers she's hit a motor scooter. There's blood, but no rider is in sight. The absence of the scooter driver is a mystery, especially to Sergeant Jack Mansfield. The scooter belongs to Jack's wife, Julie, a teacher at the local high school. She has vanished like morning fog.
