Lisa Garnder's series

I'm reading Lisa Gardner all wrong. I started with Catch Me, which is fairly late in the Detective D.D. Warren series. I followed up with other books in this line, mostly reading the more recent ones first, probably because I could get hold of them as audio books and listen to them while communting to work.

When they ran out, I moved onto the Tessa Leoni series. It's only three books, so now I'm on Rainie Conner - again, mostly backwards. I've just finished The Third Victim.

For those of you who'd like more order in their lives, have a look here: http://lisagardner.com/books. But it's not as simple as it looks, for the main characters sometimes appear in other charaters' series as cameos....
