Teach Yourself Treachery — John Burke

Rachel Petersen's husband had drowned in Holland - so who is the man who appears at her house and claims to be that husband, substantiating his claim with a passport and detailed recollections of their brief married life? From the moment the stranger calling himself Erik Flemming Petersen steps through the door, there is no peace for Rachel. She determines to unravel the tangled threads of the mystery - only to find they are more tightly woven than she could have suspected.
