Blackwork

Ferris's spooky 13th needlecraft mystery (after 2008's Thai Die ) finds Betsy Devonshire, owner of the Crewel World needlework shop, preparing for the upcoming Halloween festivities in Excelsior, Minn., along with a host of other locals, including Leona Cunningham, a Wiccan and senior partner in a microbrewery pub, who's mixing a new brew called “Don't Be Afraid of the Dark Ale.” When Ryan McMurphy, an auto mechanic who's offered his restored antique fire truck for the parade, turns up dead in a friend's basement sewing room, Betsy once again puts on her sleuthing cap. Some of the stitchers, who serve as a sort of friendly Greek chorus, are into blackwork, an intricate reversible form of embroidery. Instructions for a blackwork pattern, “Witchwork,” appear at the end. (Oct.)
