1987 - Verlangan, a former cop turned private detective, is hired by a woman to follow her husband, Jaan G Hennan. A few days later, the woman is found dead at the bottom of an empty swimming pool.
Maardarn police, led by Chief Inspector Van Veeteren, investigate the case. Van Veeteren has encountered Jaan G Hennan before and knows only too well the man's dark capabilities. As more information emerges about G's shadowy past, the Chief Inspector becomes more desperate than ever to convict him. But G has a solid alibi - and no-one else can be found in relation to the crime.
