SHOWSTOPPER

Superintendent Peter Diamond and Bath’s Major Crime Investigation Team struggle to figure out who’s responsible for a six-year stretch of mishaps plaguing a popular TV program.

Daisy Summerfield, the veteran performer on Swift who plays bad-girl heroine Caitlin Swift’s mobbed-up mother, is felled by a heart attack when she returns home unexpectedly and confronts a burglar. There’s no way her death can be murder, yet it draws attention to a mind-boggling series of misfortunes that have befallen Swift ever since Trixie Playfair, whom creator/producer Mary Wroxeter originally cast as Caitlin Swift, abruptly withdrew over a devastating panic attack and was replaced by glamourpuss Sabine San Sebastian in 2013, before shooting even began. An engineer’s been burned in a fire in a sound equipment van; two stuntmen were injured in a rooftop chase; assistant producer Dave Tudor has gone missing; Dan Burbage, who played Sgt. Monaghan, suffered permanent brain damage in a climbing accident; and Mary Wroxeter herself died of acute alcohol poisoning, presumably from four vodkas too many. To top it off, Jacob Nicol, a rigger who’d just started to work on the production, upstages Daisy Summerfield by vanishing from a location shoot at World War II airfield Charmy Down. Diamond doesn’t believe in coincidences, but he’s hard-pressed to find a pattern behind these wide-ranging calamities. Fans who join the hunt looking for a single master key may well be disappointed; Lovesey’s greatest achievement here is sifting through the wreckage of Swift to produce a logical motive and a culprit you really should have suspected.

Another triumph for a veteran sleuth who’s pretty unstoppable himself.
