I had wondered whether, having returned from India, the colour might have faded but - no. Cleverly is a master when it comes to distilling the essence of a place and time and she confidently takes the reader back into 1920s London with its dark as well as its limelit side. From the Ritz to the backstreets of Soho, Joe's London is convincing, fresh and beguiling. And in this book there are welcome flashes of humour - Joe's light-heartedness breaks through. Perhaps he's more relaxed now he's back on his own patch? The plot goes at the usual Cleverly gallop and - though I hung on! - again, I didn't guess!
