A Murder of Promise — Robert Andrews

Two women have been found stabbed to death in a public park. Washington homicide detectives Frank Kearney and Phelps want to close the case quietly without a media circus. Impossible. Victim #3 has just turned up--like the two before her--with a finger severed. A grisly clue discovered in a crack-house raid leads the D.C. team to the anonymous hunting ground of cyberspace--and on the trail of an Internet stalker whose virtual mind games have turned dangerous brutally real. For Kearney and Phelps, there's only one way to stop him. Play along ... and make it out alive.
