Richard Klinkhamer

Richard Klinkhamer (; 15 March 1937 – January 2016) was a Dutch writer of crime fiction who killed his wife in 1991 and went on to write a book about how he could have committed the crime. In 2000, he was sentenced to seven years in prison for manslaughter after killing his wife and hiding her body. Klinkhamer became the primary suspect in the police investigation for the disappearance of Hannelore: he was questioned several times and detained once. Nevertheless, the investigation yielded no concrete evidence against the writer.

In 1997 Klinkhamer sold the residence he had shared with his wife and moved to Amsterdam with a new girlfriend. Details of Klinkhamer's manuscript began to surface in the Dutch underground press, allowing him to become a minor celebrity and participate to the literary party circuit.
