The first book in this series, RUSSIAN ROULETTE, introduces us to Devlin Haskell, PI. He starts out a rather dissolute character with enough charm to keep you wanting to know more about him. Here we are, 24 novels in, and the changes are obvious. The slapstick comedy aspect is toned down, Dev is drinking far less, but the women are still there… just not as many of them. There are running gags throughout and characters we get to know that don't appear in every book.
Since the books are all from Dev's point of view, we never get a description of the man. Yes, we know what he likes to wear and, from subtle references, that he is a veteran. Other than that, we are privy to his thoughts and actions. I like to think of him as part Rockford, part Colombo, and part Bosch.
COLD CASE is a serious mystery into which Del dives headfirst after being given a book by an ailing, retired detective. Dev tells Ben Jackson that he's not much of a reader and goes home and reads the book, titled ONE AFTER MIDNIGHT, in one sitting. Jackson gifts him two more books that are read with the same enthusiasm. After devouring the first three books in this 'after midnight' series, Dev purchases the remaining three and has them sent to his Kindle. (FYI: Kindle is my choice as well.) Dev finds himself putting 'fresh eyes' on cold cases that point to a serial killer. He does this with the blessing of the St. Paul PD, and his long-time pal Lt. Aaron LaZelle.
I find that the last few books in the series have taken a turn for the more serious without eschewing the road traveled to get here. But, none of them forgo the essence of what makes them an enjoyable, page-turning read. COLD CASE will make you laugh, pull at your heartstrings, and keep you guessing till the end.
