I love to read a good old fashioned police procedural mystery. Right now I am reading the books by R.D. Wingfield with Detective Inspector Jack Frost. He is kind of like a Columbo type in a way. There are a few in the series such as Night Frost, Fatal Frost, Morning Frost and A Touch of Frost. If you like this type of mystery you may like this author!
I love a good police mystery too. Right now I'm working my way through, and am just about done, reading Tess Gerritsen's Rizzoli & Iles series which is NOTHING like the tv show. They got the characters all wrong from everything about their looks to their personalities and the stories are pretty silly compared to the books. One of the things I love the most about Gerritsen's writing is the variety of plots. They don't have the formula problem so many authors fall into.
