Another wonderful mystery featuring this investigative duo.  Sometimes I would wish for more in their relationship,  but I also enjoy following them at their own pace.  

There is a questionable medical consent scene that reminded me of the film Hysteria. 

When the doctor attempted to hypnotize her so he can use a crude vibrator on her. I mean if a lady wants to pay for that service, fine, but don't trick her into opening her legs for you.
