This is my first book by Gardiner, and it's a pretty good one. Writing and storytelling both are competently done, characters well drawn if not surprising. Gardiner's ability to create and maintain suspense, at least in this novel, is exceptional--this is an intense and creepy story that sometimes skates on the edge of being too graphic.
A few problems, though: Parts of the book (like the widespread public reaction to a morning radio talk show) just don't ring true. And really? Did no cop connected to the case recognize the quotes that appeared at the crime scenes, or think to Google them? Only after 200+ pages did the light dawn on any of the characters.
For all that, though, this is a good, suspenseful book that puts Gardiner (and the possible sequel to this novel?) on the list of authors I'll try again.
