The Frey and McGray series by Oscar de Muriel pairs two very different detectives in Victorian Edinburgh. Inspector Ian Frey, a cultured Londoner, is forced to work with Adolphus “Nine-Nails” McGray, a rough-edged Scotsman who investigates cases with supernatural elements. Their clashing personalities and investigative approaches provide both humor and tension across the nine books.
Beginning with The Strings of Murder in 2015, the series blends historical mystery with gothic atmosphere, drawing on Edinburgh’s dark history and folklore. Each case involves some element of the uncanny — from blood-stained violins to ancient curses — though the solutions often walk the line between rational and supernatural explanation. The series ran through 2022 with The Sign of the Devil.
