The Chameleon Stops at Nothing H de Roos

It's a good thing it's vacation, because Hielke and Sietse Klinkhamer are exceptionally busy. They sail from pillar to post with their boat, the Kameleon, and wherever they go, exciting things happen. One moment they have to track down a stolen tent, the next moment they arrive just in time when the doctor is shipwrecked. And then they encounter a couple of unsavory characters who are involved in a shady business...
These are situations that would keep a normal person awake for nights. However, that doesn't apply to the Klinkhamer brothers. As long as they have the Kameleon... they eagerly rush towards every danger!
