I was particularly cross with myself that I'd muddled the links because I'd read this book from the giveaway and it was great!
It's a fun high tech and computery take on a young Sherlock Holmes with a comic-artist sidekick called 'Holiga Darkly'. I love that name. The arch villain of the series is boy tech billionaire Jimmy Moriarity - a perfect antidote to David Walliams! And as we know he must be, Moriarty is B.A.D!
There's underground post office tunnels, daring roof-hopping and a great race against time – very appropriate too because this story is about a London Marathon scam. All lots of fun - 5*
