Music journalist Theda Krakow once again proves a feisty and determined sleuth in Simon's lively fourth cat-themed mystery (after 2007's Cries and Whiskers
). Theda alternates between the cat world, dominated by her pet, Musetta, and the Boston area music scene, about which she writes for local magazines and newspapers. When her retired policeman boyfriend, Bill, buys into a successful club that's a cop hangout, Theda can't help feeling a little jealous, though she admits she also has a problem with Bill's attitude—he's too patronizing. Meanwhile, contaminated cat kibble at the animal shelter run by her friend Violet may be the work of a poisoner. When Theda, guided by blood on Musetta's paw, discovers Rachel, a shelter vet, lying on the treatment-room floor with a fatal stab wound, she gets arrested for Rachel's murder. Well-drawn characters, a plot with many strings to unravel and plenty of appealing cats make this another winner for Simon. (Apr.)
