In 1527, Lachlan Maclean of Duart decided to murder his wife, Lady Catherine Campbell, a sister of Archibald Campbell, 4th Earl of Argyll. He rowed out to the rock one night at low tide and left his wife stranded on the rock to die. Looking out the next day from Duart Castle he observed the rock was devoid of life, so he sent a message of condolence to the earl at Inveraray Castle, indicating that he intended to bring his wife's body there for burial. Maclean duly arrived at Inveraray with an entourage of men and the coffin. He was immediately taken to the dining hall of the castle for refreshment only to discover Lady Catherine waiting for him at the head of the table. She had been rescued during the night by boat from Tayvallich (or possibly Lismore) that had passed by the rock.
No word was said of the incident by Argyll or his sister during the meal and Maclean was allowed to make his escape. He was murdered in his bed in Edinburgh some time later by Sir John Campbell of Calder, Lady Catherine's brother.
