Jeffery Deaver has introduced a new character. Special Agent Kathryn Dance is the star of this thriller and, for me, it’s every bit as good as one of his Lincoln Rhyme books. There are massive parallels – Rhyme is an expert criminologist who can track the movements of a suspect by the merest grain of sand that falls from his trousers; Dance is an expert interrogator who can pry into the innermost thoughts of a suspect by spotting the tiniest signals from their body language. I was impressed at the technical depth the author shows in his knowledge of the Kinesics (he even includes a list of books for further reading). And I loved the passage when Dance phoned up Rhyme for advice in the middle of the book and talks to his assistant Amelia Sachs, the other star of those books – priceless.
