'The Lonely Hour' was one of the darkest Bryant and May mysteries, infused with a sense of dread that London itself was changing beyond all recognition, becoming a steel and glass outer shell of vacant oligarch-owned luxury flats atop a nightmarish, teeming underworld of the dispossessed. Now that we find ourselves in a dystopian future nobody predicted, 'Oranges and Lemons' is, by contrast, almost continually laugh-out-loud hilarious. Like his heroes, Fowler draws deep from adversity, and the case he has conjured out of this portentous rhyme arrives with breathtaking timing. Having outwitted death and their detractors, Bryant and May now face-off their most dangerous, shape-shifting opponent yet – one who appears to have the power to act beyond the limitations of any kind of Earthly law. Fresh help comes to the PCU in the form of the luxuriantly bearded Floris and still younger, work experience protégée Sidney Hargreaves, who is proud of her gender-fluid name and seems to have a bead on Bryant. The constant fun of this wonderful and pertinent novel is how Fowler squares up his two extraordinary elderly gentlemen against the thrusting woke world, constantly finding sources of reinvention and rediscovery from the fabric of the city he loves so well. (Old) boys keep ringing!
