I Spy Mystery by Jean Marzollo (1993, Reinforced Hardcover)

This is one of the best I Spy Books ever! Each photograph is intriguing, and each riddle has a specific object to find that harks back to many old mystery and adventure books that you may have read as a child, whether it be 'the missing key to the chest', 'proof that the cat knocked over the can', 'the stolen diamond ring' or 'the pirate's X'. These types of clues add an extra dimension to the pictures and children will be more drawn into the hunt for the objects in the pictures, and as I mentioned before there is no end to the inspiration the photographs create - these are the perfect books to use to kindle a child's imagination.

It isn't just the riddles at the bottom of each page that will keep you occupied, there are more mysteries to be found at the back of the book: riddles that have to be matched to the photos, a charm bracelet that had its charms scattered throughout the pages, a cat that can be found in every page and a heart shaped box that's lost all its contents - these too are concealed throughout the book.

All in all, this is one of the better 'I Spy' books - in particular the photographs 'The Birthday Hunt', 'The Golden Cage', 'The Ghost in the Attic' 'The Secret Note' and 'Chain Reaction' are particularly well made.

P.S. (spoiler) To the reviewer who had trouble finding the 'dolphin' in the photograph 'The Naughty Kittens', it can be found on page 24 in the large tree. Look closely at the green on the right-hand side and you can see that it frames the blue shape of a dolphin against the blue background.
