THE NANTUCKET DIET MURDERS (Virginia Rich)

Eugenia Potter lacks the abrasiveness of Agatha Raisin and the sass of Stephanie Plum, but she could probably give Miss Marple a run for her money!  You may know that this is the third in the Eugenia Potter series, published in 1985, and that after Virgina Rich's death Nancy Pickard continued the series with The 27 Ingredient Chile Con Carne Murders.  Widowed Arizona rancher Eugenia Potter arrives in Nantucket for a reunion with her old gang and is surprised to see that nearly all of them are newly svelte and decidedly more glamorous than the last time she saw them, thanks to a diet guru who has set up shop on the island.  When two "accidental" deaths occur, Eugenia becomes suspicious of the charismatic diet doctor, Tony, who is raising funds for a diet clinic and whom friend Gussie seems to be considering as a potential fourth husband.  Those who enjoy technology and lots of fast paced action might want to pass on this one, but if you enjoy a good old-fashioned mystery you should consider giving it a try.  The unraveling of clues near the end leads to a surprising, but very logical and well-thought out, ending.  It all made perfect sense and the Nantucket references will be especially relished by anyone who has spent time on the island.
