good crimefighting duo
Most of the story is contained in the title. Miss Lane has been a companion to a psychic until she discovers that the psychic is a fraud. On a moments whim she goes for a job as a private detective with Mr Jasper Jesperson and also finds somewhere to live with him and his mother. Money is getting tight until a wife comes looking for help with her somnambulist husband and this lead them into a mystery about missing mediums. During the investigation they find out more about each other and about the things that can go wrong.
Interesting story and the two characters work well together. The mother is a character in her own right and you can see how resilient she is. There was a bit of handwavium about his skills but overall it was an interesting read.
