A newlywed might be newly dead in this feline-flavored mystery featuring a septuagenarian sleuth who's "an appealing Jessica Fletcher antecedent" (Publishers Weekly).   Priscilla Beckett has left a trail of suspicious exes in her wake--three former husbands who are convinced she tried to kill them. But this black-widow-to-be has found groom number four, and they're happily honeymooning at a desert dude ranch.   The fourth time might be the charm for the murderous Priscilla, which is why Rachel Murdock is called in. With her contrarian sister and stealthy cat at her side, Rachel expects to find a dead body. She does--it's just not who she thought it would be . . .   "The setting a phony dude ranch; the cast of characters, a set of ex-husbands, a lost sweetheart, a bride of uncertain antecedents, the owners and servant and guests of the ranch--and Miss Rachel to the rescue, annoying the local authorities, but turning up the right evidence at the right time . . . a pleasant antidote for the tough school." --Kirkus Reviews   Praise for Dolores Hitchens and her mysteries   "You will never regret having made the acquaintance of Miss Rachel Murdock." --The New York Times   "High-grade suspense." --San Francisco Chronicle   "For those who enjoy Little-Old-Lady detectives, this should be a pleasing mystery, particularly if active LOLs are preferred . . . Both interesting and unusual is the motive for murder." --Mystery File
