It is the picture hailed as the most convincing evidence yet of the existence of the Loch Ness monster.
Whisky warehouse worker Ian Bremner’s snap of a head and two humps in the calm waters of Loch Ness went viral online after emerging last week.
Many theories followed, including that a group of seals had somehow made their way into the Loch.
But one reader contacted The Scotsman with his own explanation - and insisted he had seen the same thing almost 70 years ago.
John Chalmers, of Edinburgh, wrote: “(Ian Bremner’s picture) reminded me of an incident on the same location in Loch Ness. I wrote a letter which you published in 1948.
It proved to be an otter when it came out on land. Had we not seen it emerge, I am sure that my friend and I would have sworn that we had seen a monster with two humps.”
Just to be sure, we scoured the files and dug out John’s letter from 1948 to prove the point.
So there you have it - are we looking at three otters, rogue seals or conclusive evidence of Nessie? You decide.
