Cambridge free-lancer Liz Conners (And Soon I'll Come to Kill You, etc.)--now helping handsome, mega-selling true-crime author Griffin Marcus research his book on the serial killing of seven (or is it nine?) Catholic women found slashed on the banks of the Merrimack--soon finds herself doubting his premise: that they were slaughtered by Henry Kmiec, imprisoned for another, unsuccessful attempt. While wrestling with her detective lover Jack Lingemann's chauvinism, and with Marcus's put-downs of her murder reconstructions, Liz and the cop-sister of a victim turn up new evidence--then the sister is killed, Kmiec becomes a suicide in his cell, and another victim (same M.O.--multiple stab wounds to the chest and neck and a jaunty green bow tied above them) is found by the Merrimack. Now separated from Jack and romancing Marcus, Liz must confront several more deaths before the grisly, if none-too-believable, resolution. More interesting as an edgy commentary on ingrained chauvinism than as a whodunit; but, still, a thought-provoking effort from an able writer.
