Warm, winsome and weight-bedeviled Savannah Reid, proprietor of the Moonlight Magnolia Detective Agency in coastal San Carmelita, Calif., goes undercover as a plus-size fashion model in McKevett's winning ninth outing, a step up from last year's family-angst-laden Death by Chocolate. When full-figured model Cait Connor turns up dead in her bathroom, stifled in a "vapor-impermeable suit," her bereaved husband blames an overly rigorous exercise routine and the manufacturer of Slenda Flakes, the cereal Cait had been hired to promote-if she could lose 30 pounds in 60 days. But after the death of another plus-size model working for the same cereal company, struck by a hit-and-run driver while she's on an early morning jog, it's clear murder's afoot. Posing as a model, Savannah gets on the killer's trail, aided by police detective Dirk Coulter and the computer expertise of her bright young assistant, Tammy Hart. The arrival from Georgia of a demanding sister of Savannah's, who suddenly moves in to follow up an Internet romance, complicates the sleuthing without slowing the plot. Food lore, a good puzzle, an exciting climax and cats with their therapeutic purring all add to the fun.
