Havank, pseudonym of Hendrikus Frederikus (Hans) van der Kallen (February 19, 1904 – June 22, 1964), was a Dutch writer, journalist, and translator.
[1] Van der Kallen was born in Leeuwarden and, under the pen-name of Havank, published over 30 crime-novels and stories, with as principal characters French police officers Bruno Silvère and Charles C.M.
Shortly after the war, he was invited to ghost-write the memoirs of Lieutenant-Colonel Oreste Pinto, the original spycatcher.
Havank also translated some 45 novels into Dutch, mainly those of fellow crime writers like Leslie Charteris, Raymond Chandler, and E. Phillips Oppenheim.
After his death, an unfinished novel was finished and published by journalist Pieter Terpstra, who continued to churn out Havank titles under the name Havank-Terpstra.
