Amazon.com Review

That monstrous villain Gary Soneji is back in Cat & Mouse, the fourth book in James Patterson's series about Alex Cross, a police forensic psychologist, but he's not alone. In seeming support of the premise that you can never have too much of a bad thing, Patterson has thrown a second serial killer into the mix: Mr. Smith, a mysterious killer terrorizing Europe while Soneji practices his own brand of evil along the Eastern Seaboard. With two killers to track, Cross has his hands full-and Patterson has another hit.

From Library Journal

Fans of Patterson's Alex Cross series will be delighted with this latest installment. Reappearing is Christine Johnson, seen in an earlier Cross novel, Jack Jill (LJ 8/96) and the principal at his children's school, and Cross has fallen in love with her. Gary Soneji, the creepy kidnapper and murderer from another Cross book, has broken out of jail and embarked on a new killing spree, again taunting Cross that he can't stop him. And one of his intended targets is Cross and his family. If that isn't enough, there's a new serial killer whose murders are so inhuman that the news media are suggesting that he's an alien from another planet. All story lines connect in this thriller, whose driving plot will distract you from thinking about its implausibilities and keep you turning pages to the last, when you'll find yourself impatiently awaiting the arrival of the next Cross novel.
