Pietro, the brave young leader of the rebels, had been captured by the soldiers of the wicked Duke Malvolio. They took him to the castle and put him into the dungeon.
"Tomarrow morning, the Duke will have you hanged," said the captiain of the soldiers. Then grinning wickedly, he slammed the heavy wooden door and locked it.
Young Pietro looked around the empty cell. It was square, with walls and ceiling made of stone. The floor was bare earth. In one wall there was a narrow window. Pietro thought he could squeeze through the window if he could reach it. But it was so high up that he couldn't reach it even by jumping.
Pietro was in despair. Tomarrow he was to die, and there seemed no way to escape.
Suddenly, he threw himself down on the floor and begain to dig in the dirt with his hands. He had thought of a way to escape through the window by digging a hole in the floor! Do you know what he planned to do?????
He dug the dirt from the far side of the cell and piled it up below the window which enabled him to reach it.
