Stuart Kaminsky's
The Big Silence is reduced to $0.99 at Amazon US, courtesy of Open Road Media. His books do show discounted from time-to-time from Open Road, usually just in time to destroy my resolve to watch my book budget more tightly....

This is the 6th in Kaminsky's Abe Lieberman series of police procedurals, originally released in 2000, featuring 60-something Jewish policeman Abe Lieberman, and his Irish parter Bill Hanrahan.
For those who aren't familiar, Kaminsky received a Mystery Writers of America Grand Master Award in 2006, and I can't think of anyone who deserved it more. His writing is dark, humorous, and full of hope, ethos & pathos.
