It is great writing and I pulled an all-nighter until I'd finished it. Wonderful technical detail, from botany to cars. The dialog is not Elmore Leonard standard. No drug-addicted prostitute I have ever known (and I've known a few) ever expressed herself in such terms as "hypothetically speaking couldn't the information the police sought be obtained over the phone." I liked finding that a witty and hard-boiled crime writer included a few decent, helpful, effective, and even sincerely religious, characters.
