Behind every mask lies a killer truth.

Mick Jagger. Bob Dylan. Paul McCartney. David Bowie. Debbie Harry. They’re icons. Legends. And together they form the ultimate supergroup - The Okay Boomers. It’s quite some band and it’s quite incredible to see them playing the Bull’s Head in Barnes on a Sunday night.

But all is not as it seems. Hiding behind lifelike masks are five local celebrities. They’re keen to keep their identities secret, but they are all unmasked when a man is found dead in the lead singer’s garden the morning after their post-gig party.

Who is the victim? Why was he wearing the lead singer’s Mick Jagger mask? And why have all the other masks disappeared? Enter DI Garibaldi, the Met’s literary, country-music loving, non-driving detective. As he investigates the five members of The Okay Boomers – a fading rom-com heartthrob, a high-profile comedian, a controversial TV pundit, a popular poet, and a national treasure – one thing becomes clear: behind every mask lies a killer truth.
