One last kill

The only member of the Seattle PD's Cold Case Unit gets assigned to an ancient case with an improbably tight timeline. The Seattle Times is about to begin marking the 25th anniversary of a series of strangulations that mysteriously ended two years after it began without a single arrest. Determined to upstage the paper, police chief Marcella Weber orders Det. Tracy Crosswhite to reopen the case, partnering her with Capt. Johnny Nolasco, the superior officer whose empty-handed heading of the original investigation marks him as anything but superior. All the mysteries of the Route 99 Killer raised back in the 1990s persist. Why did he (presumably the perp was a male) shift from prostitutes to middle-class family women with his 10th through 13th victims? Why did he carve a set of angel's wings onto the shoulder of every one of them? And why did the killings cease as suddenly as they'd started? Recognizing that Weber has staked her out as the sacrificial lamb if she doesn't produce results and that Nolasco will be as careful to avoid sharing the blame if the pair strike out as he will be to hog the credit if they find something, Tracy begins poring over the old records and quickly realizes that retired task-force control detective Moss Gunderson is acting unusually defensive, presumably because the force failed to follow up some promising leads and misplaced evidence about crucial discoveries. The providential reemergence of an earlier suspect who's just beaten a prostitute convinces Nolasco and Weber that they've found their man, but Tracy has a bad feeling about this, and as usual, her bad feelings are right on the money. Dugoni brilliantly folds murders past and present into his heroine's earlier cases and her troubled history. Copyright (c) Kirkus Reviews, used with permission.
