Tom and Mirjam may use Bouke's newly bought ship for a short sailholiday. Although they needed to beg a lot as Jeltje finds them too young to travel alone. Once they anchored at the first village, it appears there are pickpockets active. Once they are walking through a market, they meet two boys, Niels and Jimmy, their holidays turns out completely different as they expected it to go.

The sailholiday of Tom, Mirjam and Snuf looks like it will be ending in misery. There are active pickpockets and during a burglary a rare golden earring has been stolen. All the evidence points to Tom and Mirjam. There's only one way out: He wants to escape and track the real offenders.

Tom and Mirjam are getting more and more in trouble. Tom has been locked in a trapper's cabin. Snuf has been shot. Will Mirjam succeed to stay out of Tjeerd's and his son's hands? Jimmy has more difficulties to listen to his dad, but will he and his brother be able to protest against his dad?
