Dinner and a Murder (Nikki Hunter Mysteries, #3)

Dinner & A Murder is the third book in a mystery series featuring Nicoli “Nikki” Hunter, a Private Investigator specializing in covert bar and restaurant surveillance.
After surviving two recent attempts on her life, Nikki decides to do something normal for a change and attend her high school reunion, where she becomes reacquainted with an old flame, Paul Marks, now an air traffic control supervisor, and agrees to have lunch with him the next day. Over lunch Nikki becomes convinced that something is terribly wrong and, after a little persuading, Paul confides that three controllers reporting to him have died in the last two months, under suspicious circumstances.
Nikki insists on looking into the deaths and, with the help of her former mentor, Sam Pettigrew, soon discovers that Paul himself is the next target of a savage killer. So much for normal. In an effort to save Paul, Nikki, once again, must put her own life on the line.
