The Mystery Sound of a Rat

Hugh and Tellerife reveal the mystery sound of water, oh, nope. Paul from Hamilton got absolutely right, says Basil the Rat from 40 Towers. Sandra in Fitlock said, the faulty clue suggests it is a rat. And John from Turnfirmen says she saw three dead white mountain hairs along the road between Bremer and Glenshi all run over. Not sure I've seen that much before, which is sad.
