The G File - Hakan Nesser

This was all about the G file. Nothing else, he decided. No vague personal motives, no circumlocutions, just the one familiar question that had been dogging him for fifteen years. Who killed Barbara Clarissa Hennan? After fifteen years, the G File remains the one case former Chief Inspector Van Veeteren has never been able to solve. But when a woman reports her father - a private detective linked to the investigation - missing, Van Veeteren returns to Maardam CID once more. Jaan G' Hennan remains the prime suspect in the case and Van Veeteren knows only too well the man's dark capabilities. Can the former detective keep his head and finally solve this terrible crime?
