Meet Knightley and Son - two great detectives for the price of one ... Darkus Knightley is not your average 13-year-old: ferociously logical, super-smart and with a fondness for tweed, detective work is in his blood. His dad Alan Knightley was London's top private investigator and an expert in crimes too strange for Scotland Yard to handle, but four years ago the unexplained finally caught up with him - and he fell into a mysterious coma. Darkus is determined to follow in his father's footsteps and find out what really happened. But when Alan suddenly wakes up, his memory is wonky and he needs help. The game is afoot for Knightley & Son - with a mystery that gets weirder by the minute, a bestselling book that makes its readers commit terrible crimes, and a sinister organisation known as the Combination ... A funny, warm, fantastical crime caper with an unlikely hero and a brilliant comic cast, perfect for fans ofSherlock and criminally good storytelling.
