Richard Klinkhammer, a Dutch crime writer, wrote a book which explored seven ways to kill your spouse in great detail. He proposed this book to his publisher a year after his wife had disappeared, a crime which he was suspected of.
The manuscript was rejected for being too gruesome, but a few years later details of the manuscript began to surface in the Dutch underground press. With his new cult fame, he would appear on television occasionally and moved to Amsterdam with his new girlfriend, where the coverage of him had gathered him a small following among crime writers.
He only stayed in Amsterdam for three years, however, because in 2000, the new owner of his house found the body. The police had already searched the house and even had a plane fly over to do thermal scans of the property, but they never found anything. The body was buried under the shed's concrete base. At age 62 he was arrested and confessed to murdering his wife.
