The Black Echo - Michael Connelly

I recently bought a Kindle short story which is by Michael Connelly and Dennis Lehane and has Harry Bosch and Patrick Kenzie teaming up to solve a crime in Boston.

 

I've read all of Lehane's Kenzie and Genarro stories, but haven't ready any of Connelly's books about Harry Bosch, so thought I should find out a little bit about Harry before I read about their meeting.
