Perish twice

the long version

"In Perish Twice, Sunny comes to the aid of three very different women, with deadly consequences. Hired by prominent feminist Mary Lou Goddard to protect her from a series of threatening phone calls and shadowy pursuers, Sunny must contend with Goddard's reluctance to reveal all she knows about the unwelcome attentions bestowed on her. When a member of Goddard's staff is gunned down, it's called a case of mistaken identity. And when the murder suspect is found to have eaten his own gun, two cases are settled, though neither to Sunny's satisfaction." "The murder investigations lead her to the Boston underworld, where her footing, despite backup from her close friend Spike and ex-husband, Richie, is treacherous at best."--BOOK JACKET.
