This is my favorite kind of murder mystery. Scotland Yard in the early days just after Jack the Ripper disappears. The Yard has a new murder squad and a doctor who started his own morgue after seeing the horrible treatment that victims were given. Dr. Bernard Kingsley is the coroner and treats the dead with respect and also realizes they hold most of the clues of their murders. Detective Inspector Day is a new member of the Yard and he proves to his fellow Bobbies that he can do the job. There are several cases going on at the same time so this book keeps you thinking. I am happy to find a new author that I will follow.
