The Secret Seven by Enid Blyton

I like this book because of it has fantastic adventures. At the greenhouse (the normal setting) Peter and Jane were thinking about doing another s.s. meeting. So they wrote some letters to the members. They replied and said can or might be able to come. The adventures are like finding a member of the s.s. like finding Jack because they did not know what had happened to him.Another thing they have adventures with is people who are criminals they told the police about like this one. Four people who did things with trains by making the trains go the wrong way. When they were done with the police celebrated and said the Secret Seven are the best society ever.
