Murder at Fenway Park, by Troy Soos. The first in a series of "Mickey Rawlings" baseball murder mysteries. I read them all. Great use of actual players and baseball atmosphere from the 1910's and 1920's. This is the kind of baseball fiction I would like to write myself.
Caleb Carr is just magnificent. This book is set in the late 1800's of New York City. Because the mentally ill were deemed aliens of society, those who worked with them were not called psychologists but rather, alienists. Amazing page turner if you're into psychological thrillers! Loved this book!
