A wickedly funny, edge-of-seat crime caper featuring a brilliant cast of characters and one utterly heartwarming canine pal. Darkus Knightley, tweed-wearing, mega-brained, thoroughly logical 13-year-old investigator of the weird, was just getting used to having his dad back in his life.

Then Alan Knightley went off-radar, again, leaving Darkus with a traumatised ex-bombdisposal dog as his only partner in crime-solving. Now things are getting even stranger. Family pets are being savaged by a beast on Hampstead Heath. A top policeman has been tracked and attacked by a particularly aggressive canine. And two curiously alert hounds seem to be watching Darkus’s house.

No one is using the word werewolf – yet – but as the full moon approaches, it doesn’t take Sherlock Holmes to work out that someone or something sinister is messing with the minds of London’s dog population. A mysterious canine conspiracy is howling for the attention of Knightley & Son . . . Criminally good detective adventure, perfect for fans of Sherlock and sharp-minded sleuths of all shapes and sizes . . .
