“Grey Somerled came to Colonsay, they say, in the capacity of factor. But he neglected his duties, imposed penalties and hardships on the innocent and defenceless tenants, and generally made himself so disagreeable that at last it was decided to take revenge upon him, previous warnings having been no deterrent.
“Like Rory Mor of Dunvegan, who slept best when he was within hearing of his ‘nurse’, the waterfall, Grey Somerled was wont to be lulled to sleep by the grinding noise of a quern placed near his head. When he retired for the night, one of the servants had to turn the quern-stone by his pillow, and keep on turning it, lest he woke.
“It was recognised that any attempt to surprise Grey Somerled during daylight was foredoomed to failure. So, a plot was laid to circumvent him during the night-time. His enemies entered into a conspiracy with one of the servants that she should allow them to invade Dun Gallain after he had fallen asleep. When they arrived, one of their number relieved the woman at the quern, and proceeded to turn the stone without intermission. But he was not too skillful at the turning; and his harsh and irregular grinding soon woke the sleeper. Ere Gey Somerled had had time to consider the matter of resistance, his foes were upon him. They carried him away from Dun Gallain; and tradition in the islands of Argyll has it that, in great privation, he spent the remainder of his days in a bee-hive house of stone, situated on the farmlands of Machrins.
“One night – so the story concludes – a huge boulder from the roof of the bee-hive fell in, killing its unhappy inmate. So as to identify the spot where this tragedy happened, the islanders raised on it the cairn now indicated on the Ordnance Survey Map as Carn Shomhairle Liath – that is to say, Grey Somerled’s Cairn.”
