How to Read the Jack Stalwart Books
Read the fourteen Secret Agent Jack Stalwart missions in numbered order. Each country offers a largely self-contained case, while the mystery of Jack's brother develops across the sequence.
Secret Agents Jack and Max Stalwart is a separate four-book follow-up line starring both brothers. Read it after the original fourteen rather than combining the two numbering systems.

For parents
What Parents Should Know
The missions include kidnapping, poaching, thieves, dangerous animals, natural disasters, weapons, and children placed in peril. Action stays appropriate for early chapter-book readers and usually resolves quickly.
Each story introduces a different country and landmarks, but the brisk spy-adventure format simplifies cultures and international problems. Parents can use the books as a starting point for learning more rather than as a complete picture of a place.
