What Maggie does... Maggie Russell, a police reporter in Sacramento, works the night shift. She's divorced and the mother of a very active three-year-old son. Maggie may not have much time for a social life, but she's recently begun an e-mail correspondence with a man named John.

What Maggie knows... She's finally stumbled on the big crime story that will truly establish her career - if it doesn't end her life. A serial killer who moves from one city to the next. A murderer who chooses a female reporter and writes her letters . . . before he kills her.

As if things aren't complicated enough, Nick Sorenson, the paper's new photographer, seems to be taking an unusual interest in this case. And in her.

What Maggie doesn't know... Nick's an undercover FBI agent tracking the killer and keeping an eye on Maggie - at work and through his e-mail persona "John." Maggie doesn't realize that she's falling in love with a man who's not what he seems to be. A man whose deceptions may save her life.
