We also know The Detective’s Handbook has been given a terrific production. Jonathan Biggins’s direction doesn’t let a sight gag or piece of comic timing escape, Michael Tyack is the expert musical director and James Browne’s design is a marvel of elegance and economy. The cast is absolutely top drawer. Writer Ian Ferrington has a way with words, no doubt about it, and Olga Solar’s score is unfailingly attractive and stylish. Rap rhythms, jazz moods and smooth 50s ballads go down easily and the laughs come thick and fast if you’re partial to a pun. This loving production gives The Detective’s Handbook more than it warrants but let’s call it an investment in the future. It would be good to think Ferrington and Solar are already working on something else. Also starring Tony Cogin and Sheridan Harbridge (pictured).
