Hoch's annual short story roundup includes three not-to-be- missed: Ruth Rendell's ``Mother's Help,'' in which what goes round comes round inexorably; Peter Lovesey's ``The Crime of Miss Oyster Brown,'' in which a pair of set-in-their-ways spinster sisters arouse the interest of all-too-helpful villagers; and Wendy Hornsby's Edgar-winning ``Nine Sons,'' a sad commentary on the fate of rural daughters. Bill Pronzini is represented by ``La Bellezza Delle Bellezze,'' which he enlarged to become the novel Epitaphs. Also on hand, a Thirties locked-room puzzle featuring a big band, a black doctor, and a needle from editor Hoch; a sour tempting- fate-with-a-gun-in-the-pocket disappointment from Lawrence Block; and a brother's revenge from Brendan DuBois. Plus works by Stuart M. Kaminsky, Doug Allyn, Barry N. Malzberg, Peter Robinson, and Carolyn Wheat, none of which is memorable. This latest edition of 12 stories includes lists of: this year's award-winning novels/short stories; anthologies; biographies; and a necrology.
