The adventures of the Irish terrier Michael began the moment he ran to the shore during a walk. Here he was picked up by the steward of the schooner McCambo, Dag Daughtry. Dag decided to sell the purebred dog at the nearest port, secretly brought Michael onto the schooner and hid him in his cabin. Michael was given another name. He became very attached to his new owner, with whom he would have to go through many happy and sad days, break up after a series of dramatic events and meet again.
