Florida Roadkill

Florida Roadkill is the first book in the unnamed series of books by Tim Dorsey which were centered on his character Serge Storms. It was published in 1999 by William Morrow and Company, an imprint of HarperCollins.

Note that although Triggerfish Twist was written several years later, the events of Twist take place at some unspecified point in the middle of those in Florida Roadkill (as Dorsey's web site puts it, Tim didn't know what he was doing and killed too many people he later decided he needed).
