My son aged nine adores these books. The protagonist, Tim, and his canine sidekick, Grk, always become ensnared in some quite serious adult scam - in this story they find themselves on a rich man's island paradise having to rescue a laboratory-full of stolen animals. Tim can often find himself in frightening situations, but these, to my mind, are handled very sensitively. Above all, it's always his quick-witted resourcefulness and courage that win the day - not a magic wand or the arrival of the Cavalry at the 11th hour - and that's empowering to children and one of the many strengths of these books. We enjoy the inventive plotlines, the colourful villains, the vivid settings (each story has a different geographical background), the topicality of each story and the wry, lively writing. We're on Eurostar to Paris now with Grk Takes Revenge and learning all sorts of useful things on the journey. Vive Grk!
