Summary: Ruairidh was telling us about ‘the adder man’, Tormod an t-Seòladair. He was also keen on eels. He found out that the eel rests in the winter. It’s rather like hibernation. Tormod also had his own opinion on the Loch Ness Monster. Find out more in this week’s letter. Accompanying Gaelic text, grammar points and vocabulary are all available at bbc.co.uk/litir
