2 Dogs

The three sleuths of the title are sisters Barbara Ann Evans, the "serious" one, Faye Burner, the hard-working, "responsible" one, and Margaretta "Retta" Stilton, the youngest "pretty" one. The two dogs are Retta's adorably oversized Newfoundland Styx and the motley mutt Faye rescues from the side of the road. The one murder is that of Stacy Kern, the wealthy wife of Winston Darrow and the sisters' newest client.
