Colin Cotterill's crime books featuring Dr Siri Paiboun.
Set in 1970s Laos, they feature the elderly Dr Siri who is both National Coroner and a late-onset shaman. As well as crime and resolution the books are witty, satirical and ... dare she say it ... have a supernatural element.
It do make Mrs D remember her librarian days in the "halls of academe" when her first humble post was as an assistant in the South East Asia Department.... long, long ago... This was not a supernatural experience in the main but ... come to think of it ... was prob'ly about the same time the admirable Dr Siri be operating.
