These are very nicely written with lots of great vocabulary which I love especially since I have the click link for full definition!  The mysteries are not written from the point of view of the doctor, so you get to wait until the testimony to see if your accused will be found guilty! Some follow the "Watson" style character, some follow the innocent person caught in a horrible web of guilt, and some even follow the perpetrator! They are quite wonderful. Slight warning for you to be aware that in those times often the 'gentlemen' and 'ladies' (whites) are considered less "suspicious" than the "foreign" characters. But if you only read books with modern mores you will miss much.
