Anyone ever come across James Melville's Inspector Otani books? They all appear to be out of print now. The titles are nicely cheesy, such as "Sayonara, Sweet Amaryllis", "Go Gently, Gaijin", "Kimono for a Corpse" etc. The blurb from "Wages of Zen":
They seem like a racier version of Timothy Henion's Inspector Morimoto series.Superintendent Tetsua Otani of the Hyogo Prefectural Police and his wife Hanae enjoy a comfortable life. Murder is a rare crime in Japan. But an Irish Catholic priest has been found dead in the snow at a sacred Buddhist temple and it looks like murder. So which one of the five foreigners who has gathered to learn and practice ancient teachings of the Zen masters an the the Chisho-ji Zen Study Center could have done and why?
