SHARP FORCE

A Christmas bout between Kay Scarpetta and the Phantom Slasher.

But first, Scarpetta, Virginia’s chief medical examiner, has to figure out how software designer Rowdy O’Leary died. Fished from the Potomac River on Christmas Eve six years after a hit-and-run driver left him permanently disabled and a week after he plunked down the cash for a pricey emerald ring, he fell off his fishing perch and drowned—or did he? Scarpetta’s examination of his body is cut short by two disturbing developments: the discovery of an unidentified woman’s remains buried on the grounds of Mercy Psychiatric Hospital, and celebrity TV reporter Dana Diletti’s report that the red-eyed ghost associated with the Slasher’s three murders has floated through the window of her home. She’s got video, too, and the apparition looks real and scary. The final blow to Scarpetta’s plans for a Christmas getaway with her husband, Secret Service forensic psychologist Benton Wesley, is an attack on an Alexandria home that kills Mercy psychiatrist Georgine Duvall, who used to treat Scarpetta’s niece, Lucy Farinelli, and nearly kills graduate student Zain Willard, White House intern and nephew of presidential candidate Sen. Calvin Willard. This time the Slasher’s ghost has been spotted on the scene by none other than Pete Marino, head of investigations for the medical examiner’s office and Scarpetta’s longtime sidekick. Cornwell’s use of Robbie, Zain’s robotic dog, and Janet, Lucy’s AI companion, integrates the futuristic elements she favors more successfully than in her recent outings. But the solutions to all these mysteries will leave fans of the venerable franchise pursing their lips rather than gasping in awe.

Come for the forensics, stay for the nonhumans.
