Another Secret Seven story along the same lines we are used to. Susie is still a pest, although she is a great foil for the Secret Seven. She is intelligent, although annoying, and you can't help feeling like she has a point in her feud against the Secret Seven, since they exclude her from their adventures.

Anyway, here we have a telescope that the children use to see strange goings-on in a ruined castle. The story is OK, without being anything special, but it made me remember with fondness the superior castle story by Blyton, Castle of Adventure. Then again, the Adventure series, targeted to older children, was always more exciting and less simplistic than the Secret Seven. ( )

Have you ever noticed how real life children are never as organised as the Secret Seven. How do they manage to get through so many books without feuding? ( )
