Murder in the Charleston Manner — Patricia Sprinkle

A LETHAL DOSE OF SOUTHERN COMFORT
"Trouble follows that woman like fleas follow a dog" her father had always said about Aunt Mary. Sheila Travis ruefully agrees when she is dispatched by her colorful aunt to Charleston to "investigate" some mysterious accidents occurring at the historic home of Mary's childhood friends, Dolly and Marion.

Sheila's hostesses are a monument to Southern hospitality and though a master at protocol, the former ambassador's wife feels boorish by comparison. But this isn't a social visit -- Sheila has a job to do, even if she's initially inclined to write the accidents off as coincidence. The first murder changes her mind. The second begins to unearth dark secrets amidst the roses and honeysuckle. Wills and family history come under close scrutiny as Sheila closes in on a killer... unwittingly putting herself in deadly danger.
