The steamy summer streets of Washington are no match for the phone lines of Fantasy, Inc., where every man's dreams come true. The "hotline" works perfectly for its anonymous clients, and the teachers and housewives who moonlight as call girls...until a brilliant madman plugs in with twisted passion, tracks down "Desiree" and murders her.

A different kind of passion brings Grace McCabe and Ed Jackson together -- a passion for each other...and for justice and revenge. Grace, the bestselling mystery writer, is determined to trap her sister's killer, to bait him with the same seductive voice that triggered his deadly lust. Ed, the cop assigned to the case, knows he can't stop her, that he can only protect her.

Somewhere in the darkness, someone is waiting, listening for the voice that will bring him back to the scene of the crime for one last thrill, promising ecstasy -- and death.
