A fun interactive book jam packed with puzzles to exercise the “little grey cells”. This would be perfect for ages 7 - 12 with many different types of puzzles to solve and a story to follow along there’s something for everyone.

A puzzle book designed to put the young reader into the world of cosy crime. In the first instance (once a couple of easy enough tasks, and one of those chains-of-cogs things I never ever get right) you're to work out who nicked a puppy from a village fete. Oddly, this is pretty awkward stuff, as first it narrows down the suspects for you to four then three, and then starts yacking on about each and every initial suspect (many of which you have eliminated) and what blades they were using on the day. Surely the target reader could do without such confusion – and the early instance of them knowing the book is doing daft things; it's hand-holding to the right conclusion for the newbie, perhaps, but in waffling about the innocent can't be said to share a great detective's brain and insight.

And the problem with this kind of book is you really need to be on the right wavelength, both to enjoy it, and to comply with it. Let me paraphrase a part of the third part, where you're indulging in a bit of breaking and entering – "You see a keypad and a squiggle. You work out that, if only you could see the squiggle better, you'd know it contains geometric shapes to tally and put in the keypad. But which of these three enlargements are the real squiggle (answers on p178)? (Turns page to p50) You're right, it was C! So go on, count things up..."

Very rare are the instances where these books can force you to generate the right answer before you can progress with the problem. I mean, I know it's cosy crime and all that, but how cosy is it to not actually need to work out which key is missing, what numbers the accursedly obligatory sudoku are providing, and so on. It then is a book that has to believe it's succeeded – it has to take it on trust that you've done each and every task, worked through each and every code and maze and whatnot as and when demanded. Having done that diligently enough you'll find that all told the story is an engaging one – richly involving you in a world of unlikely artworks, ferrets, and trapdoors in churches. But a book like this needs to minimise the chances of you not playing along, and this one with its weird attitude to suspect lists at the start did not play ball enough for all of us to do so too. Add in the one-use-only nature of such a volume, if you do indeed join in properly, and three stars is a maximum mark.

Really great puzzle book with some good humour. I've recommended this in my school reading newsletter.

This is a most unusual book which the whole family can enjoy. The puzzles and codes kept me and my granddaughter amused for many hours.. The challenge to solve the kidnap of Dave the Dog is filled with humour with challenges in every chapter. We thoroughly enjoyed this book and hope there will be more in the series for our family to enjoy.

You are now a member of the Hartigan Browne Detective Agency, Browne being arguably Britain’s greatest detective. His success in previous cases has led to him being overworked and in need of some assistance – this is where you come in. Dave the dog has been pup-napped and it is up to you to find out why and who the culprit is. This is the first of many puzzles that will, hopefully, lead you to the discovery of the Dumpleton Diamond.

Although this has been published by Macmillan Children’s Books, it is most definitely not just for children. The puzzles are challenging enough for adults to get enjoyment from with clues to help younger children if they get a bit stuck. There is a good range of puzzles, from codes to logic problems, picture puzzles to anagrams so that there is something here for everyone.

The story that runs through the book is a good one and kept me engaged throughout – this is one of those books where you keep telling yourself, ‘one more page…’ until you have finished it in a couple of sittings!

If you are looking for a slightly different read, one that will get the old grey matter working, then this is the book for you. Great fun for all the family, I am pleased to see that there is already a second book in the pipeline!

I think this is a brilliant book and it would make for a super gift for young super sleuths!
You begin the puzzles straight away and everything comes down to the reader to discover identities, clues and putting the pieces together.
I had a lot of fun filling in the pages and solving the mysteries.

Add a pencil and some notepaper and you have the perfect present!

My daughter has been enjoying logic problems and puzzles recently so I wanted to take a look at Cluedle as a possible purchase - will definitely be buying!

There looks to be a good variety of puzzles in here that should keep chikdren interested and their brains ticking over, I'd say for kids aged about 8-11, maybe 12.

The theme running through isn't the strongest, but I still think it's decent compared to normal puzzle books that are completely unrelated to the next puzzle.

A fabulous puzzle book for a pre teen to spend a rainy afternoon with. Lots of different types of puzzles keep the interest going. I, going to buy it for my grandchild. Not sure why it wouldn’t send to kindle though, perhaps because of the formatting.

A great book for budding detectives! I’d say this book is aimed at 8-12 year olds, and is more along the lines of puzzles, rather than stories that you have go solve
