Speurhond Willem op reis

Adriaan is a bit of nerd and not particularly good at anything. But his dog, Willem, is another story! He is a super secret agent spy dog, known and feared all over the world.

Under the pretence of going on a soccer tour Adriaan and Willem make arrangements to travel to Istanbul, where, in true espionage-style action, Willem’s contact awaits.

From there the hunt for the villain Sybrand Swiffervalk leads them to Venice, Paris, Amsterdam and finally to England.
