Dating can be dangerous, so clients who can afford the services of eccentric Russian "baroness" Grusha Olinetsky, are willing to pay the hundred-thousand dollar fee she charges for an introduction to their perfect mate.

When Olinetsky hires Claudia to come to Manhattan and help her uncover apparent screwups made by her nemesis, the assignment puts her at odds with her romantic partner, Detective Joel Jovanic, who suspects that Grusha herself is trouble. Drawn into the feckless lives of the rich and single, Claudia delves into a twisted world of love and lies fueled by desperation. But desperate enough to kill? Clues in the suspects' handwriting might help Claudia save Grusha's already dubious reputation before the names of more victims are scribbled into someone's little black book.
