The Gang and the Treasure Non-Treasure 2

Every town has its secrets waiting to be discovered. But not every town has its own castle – and castles usually hide the most secrets of all. There's one near Brod, or at least, there used to be; now it's just a ruin. A mysterious one. Who actually had this majestic castle built? Why is it now just rubble? And most importantly – where does the forgotten tunnel lead, the one discovered by a group of four curious children? In their quest for mysteries, the heroes of the book The Gang and the Journey Against Time will learn a lot of interesting things about the Middle Ages. And as is often the case – there will certainly be no shortage of pleasant and unpleasant surprises!
