Dark arts

1889, Edinburgh. A large family arranges a spiritualistic session - the popular fun of the Victorian era. It is invited to conduct a fortuneteller named Madame Katerina. But the next morning, after the session, all invited are dead - with the exception of Katerina. The fortuneteller faces the execution for the murder of six, but she swears that she is innocent. Two inspectors of the Scottish police - nine -falling McGreu, known for their boiling nature and love of the occult sciences, and Ian Frey, the chopping dandy with excellent deductive abilities, will unravel this mysterious business - with excellent deductive abilities. Freya and McGrea are waiting for a lot of tests - from a judicial confrontation with the meanest prosecutor in the city before meeting with the underworld itself.

A stunning Victorian detective with a couple of damn charming detectives.
You will not want to reveal a riddle, just to stay with these gentlemen longer!
