After twenty-fives years on the job, NYPD Lieutenant Greg Webster retired to a small Kansas college to teach classes in Criminal Justice. Greg looked forward to the move as a well-deserved rest for himself and his social-worker wife, Carolyn, but before even a year had passed Carolyn was dead, killed in an apparent hit-and-run accident. Greg was dazed and heartbroken until, as a class project, one of Webster's students began researching local womens' violent fatalities and Carolyn's death began to look more and more like the latest in a series of murders stretching back over several years.
But why would a successful serial killer tempt fate by targeting a retired police officer's wife? Maybe because it was all becoming too easy for him, too many easy targets. Now the murderer, who called himself The Watcher, wanted more of a challenge, an opponent tougher than the local campus police. But in taking on Greg Webster the Watcher made a serious mistake. He should have heeded the old warning: Be careful what you wish for.
