It's summer again and some of us think Roy's plan for our Youth Club's holiday project is fantastic. We've raised a lot of funds, so why not use them to build a proper crossing at the Stepping Stones Bend on the River Rye? That way the old folk, and young families too, will be able to reach the local nature reserve on the other side of the river much more easily.
But Club is deeply divided on the issue and so is the Robinson family, not least my young brother Tony. Feelings are running high - but surely not high enough for someone to stoop to SABOTAGE? Yet someone is definitely determined to wreck our project. Who can the secret enemy possibly be......?
