Here is a Famous Five Adventure Game Kit of The Sinister Lake Game, the story  by Enid Blyton. 

All in a plastic outer case there is a book a map, a rucksack that contains binoculars, a measure card, a code book . Also a lunchbox with 3 picnic cards . 

Mysteries to solve, codes to crack and map to follow. 

This is a very interesting game to play. The book is in good condition generally but the pages have come adrift from the spine so is in 3 parts but still usable nothing missing. All the parts of the accessories are there apart from the dice which I hope you can use a dice you may have already although I know it is a different sort of dice.   Please see photos .
