In the wake of Sherlock Holmes’s massive success the world was so overrun by lady detectives, French detectives, Canadian lumberjack detectives, sexy gypsy detectives, priest detectives, and doctor detectives that there was a shortage of things to detect. Why not ghosts?
And thus was spawned the occult detective who detected ghost pigs, ghost monkeys, ghost ponies, ghost dogs, ghost cats and, for some strange reason, mummies. Lots and lots of mummies. Besides sporting ostentatiously grown-up names that sound like they were randomly generated by small boys wearing thick glasses (Dr. Silence, Mr. Perseus, Moris Klaw, Simon Iff, Xavier Wycherly) these occult detectives all had one thing in common: they were completely terrible at detecting.
