Someone is killing randomly - mainly black and Hispanic women - but the police seem reluctant to recognise that there is a serial killer on the loose. The murder victims are, for the most part, unimportant, the detritus of a big city, people on the margins and in the shadows. But Washington homicide detective Alex Cross is determined to root out the killer and establish the connections between these apparently random crimes.
The killer, as we are quick to learn, has a solid disguise and the skills to employ misinformation and disinformation. He also has a penchant for playing games, and he appears to have read "The Dice Man". Who he kills, where, and when, are all largely random decisions - a sure way to camouflage his insanity and disrupt any pattern to the crimes.
Thus we enter a cat and mouse game, intriguingly written in two narrative voices. Cross appears in the first person, the murderer and the incidentals in the third person. It's an intriguing technique and helps elaborate a sense of distance between hunter and hunted. Patterson writes with page-turning ease and you are quickly swept up in the story. There are unsatisfactory elements - a computer geek magically comes up with answers at the right time, there are a couple of over-stretched coincidences - but it's a helter-skelter, entertaining tale and one which fans of the thriller genre will love.
