Rain was falling heavily in the River Po catchment area in northern Italy and the old hands knew that it would burst its banks and there would be flooding. But even they are surprised when they see Tonna's barge setting out downstream. He knows the river well, but his course out of the mooring was erratic and when the barge was eventually found Tonna was nowhere to be seen; the barge was deserted.
