ON HARROW HILL

The seventh Dave Gurney thriller opens with a lesson on the unreliability of eyewitnesses and then takes up a series of lurid crimes committed in a village where nothing is what it seems.

Super-detective Gurney, retired from the NYPD, is still periodically drawn into especially difficult investigations, which is why his former partner Mike Morgan has called. Morgan's departure from the NYPD was not as unblemished as Gurney's, but he has landed well and is now chief of police in Larchfield, home to a number of wealthy individuals and mostly the creation of the Russell family. When Angus Russell, the current patriarch, is murdered in his own mansion, there is considerable uproar, and Morgan asks Gurney to help manage the investigation and divert a little of the world's attention from himself. The crime-scene evidence points directly at Billy Tate, a man who had strong motives for murdering Russell but who was, frustratingly, already dead, the victim of a lightning strike the day before Russell was killed. From this puzzling but admittedly gripping beginning, the investigation uncovers progressively more baroque variations on the theme of deceptive appearances. First, it's established that Tate might have survived the lightning bolt and the subsequent fall from the church steeple, because he was a tough guy and, well, who knows about lightning? More bodies pile up, and the emergence of several characters who also might have wanted Russell dead suggests that Tate may have had help. Morgan, while not actually obstructing the investigation, seems to have reasons to want the case closed quickly. At each turn, Gurney helps to classify, consider, and clarify evidence and the theories the evidence gives rise to, but he, too, is somewhat misled. The residents of Larchfield are an admirably unlovable bunch, seething with resentments and snubbed privilege, and Gurney and his wife are pleasantly down-to-earth, but overall the plot mechanics reach too far beyond the merely astonishing.

Well-drawn characters and a dynamic situation but in the end, just a bit too much.
