An obsession with history has cost Helen Kovacs her life. Her research into the Nazi occupation of Eastern Europe was a secret she kept from even her closest friend, Faith Lange. Now Faith, retracing Helen's last steps, is convinced that the man the police have arrested is not the killer. Journalist Jake Denbigh's investigations have led him to the same conclusion. Faith is disturbed by Denbigh's digging. Among the refugees from the concentration camps of Minsk were war criminals masquerading as victims. Could Faith's beloved grandfather Marek be hiding such a secret ? And does the reason for Helen's murder lie in the mass graves of the Kurapaty Forest - or much Gloser to home ?
