In the days when King Frederik the Second of Denmark ruled over Bohuslen there dwelt at Marstrand a poor hawker of fish, whose name was Torarin. This man was infirm and of humble condition; he had a palsied arm, which made him unfit to take his place in a boat for fishing or pulling an oar. As he could not earn his livelihood at sea like all the other men of the skerries, he went about selling salted and dried fish among the people of the mainland. Not many days in the year did he spend at home; he was constantly on the road from one village to another with his load of fish. One February day, as dusk was drawing on, Torarin came driving along the road which led from Kungshall up to the parish of Solberga. The road was a lonely one, altogether deserted, but this was no reason for Torarin to hold his tongue. Beside him on the sledge he had a trusty friend with whom to chat. This was a little black dog with shaggy coat, and Torarin called him Grim. He lay still most of the time, with his head sunk between his feet, and answered only by blinking to all his master said. But if his ear caught anything that displeased him, he stood up on the load, put his nose in the air, and howled worse than a wolf.
