The secret envelope

Imagine being a 10-year-old boy with a humdrum and unexciting life, who is suddenly thrust into a perilous adventure involving kidnapping, international espionage, and a pair of menacing crooks.

George is that boy, and he has to use all of his ingenuity and courage to try to outwit the crooks and protect the secrets that he has been entrusted with.

You wouldn't think he would stand much chance, and neither does he, but he feels obliged to do his very best to help out the stranger who passed the secrets on to him in a moment of panic.

The police don't seem to be any use at all, and the poor lad, together with his friend John, are forced to use all their wits to try to get themselves out of trouble.

None of this should happen to an ordinary schoolboy who is just about to finish primary school, but George finds himself tangled up in the crooks' plans just the same, whether he likes it or not.

He finds his adventure terrifying and feels helpless when confronted by the dangerous villains.
