Gallyon van Vessem

A zoo veterinarian gets caught up in a grisly adventure as she finds herself leading the city-wide hunt for a monstrous lion terrorizing the Dutch capital of Amsterdam.

The three crooks lure Bassie and Adriaan to Curacao to take care of them once and for all. This doesn't go as planned. Back in The Netherlands Bassie wins a trip to the USA in a TV quiz and takes Adriaan on a tour of the whole country. What they don't know is that de Baron, B100 and Handige Harry are on their trail.
