Two things immediately endeared me to the the main character in the book (a.k.a. the author, I imagine) First, he is a fan of country music, and was quick to reference the divine trio of Emmylou, Dolly and Linda. Second, he is no fan of the more self indulgent excesses of modern jazz. But there’s a good story here, too.

The Okay Boomers are a celebrity amateur rock band. In two ways. Confused? The five-piece outfit are actually media celebs themselves, but they wear masks on stage. Masks of Bob Dylan, Mick Jagger, Paul McCartney, Debbie Harry and David Bowie. They play a pub gig in the affluent London district of Barnes, and have an ‘after party’ at the mansion owned by one of the band members. When a body is discovered the next morning, dead as can be on the gravel underneath a balcony,  DI Garibaldi hops on his bike (literally, as he doesn’t drive) and joins the investigators at the crime scene. The dead body is eventually revealed to be that of Frankie Dunne, an unremarkable young man who – apparently – was completely unknown to any of the Okay Boomers.

Bernard O’Keefe has some sly fun with a couple of the celebrities. There’s Larry Benton, a former footballer turned presenter who sees himself as the champion of middle class liberal sentiments, and Charlie Brougham, the handsome, floppy-haired toff whose boyish charm once graced many a British comedy drama. Hmm. Let me ponder. Who could he have been thinking of?

As you might expect, beneath the veneer of showbiz cameradie, the members of The Masked Band have, in private, little good to think or say about each other. In a rather neat bit of technical business Bernard O’Keeffe has five of the band masks go missing from the crime scene, with the  only surviving mask – that of Mick Jagger – placed on the face of the defenestrated corpse, thus placing the latex Bowie, Dylan, Harry and McCartney faces out there in the community and ready to be used and abused.

We know from the brief and enigmatic prologue, that a young man who has drunk well rather than wisely heads of in search of his girlfriend and his missing ‘phone. He arrives at the house where he thinks both are and ….. end of prologue.

Were you to organise a convention of fictional Detective Inspectors you would need something larger than the average town hall. So how does DI Jim Garibaldi measure up? Italian heritage, obviously; lapsed Roman Catholic, parents died together in a road accident – hence his refusal to learn to drive; his marriage broke down, but he has a bond with his son, renewed every time they go to Loftus Road to watch QPR; he is widely read but wears his learning lightly.

Garibaldi is an engaging central character. Like all the best fictional DIs, he is prepared to think outside the box. The quirky copper resolving cases that baffle his senior officers is an oft repeated trope in police procedural novels, but it works well here. The identity of the person responsible for Frankie Dunne’s death does not exactly come out of the blue, but it is cleverly hidden until the final pages. This is a thoroughly engaging police procedural tale with just the right blend of mystery, dry humour and credible characters. The Masked Band is published by the Muswell Press and is out now.
