In Thurso others find calm (6)
I believe the answer is:
soothe
'calm' is the definition.
(I know that calm is a more specific form of the action soothe)
'in thurso others find' is the wordplay.
'in' says the answer is hidden in the clue.
'SOOTHE' is hidden in the letters of 'thurso others find'.
(Other definitions for soothe that I've seen before include "Assuage, calm" , "Calm down, placate" , "Calm; relieve pain" , "to settle" , "'Console, comfort (6)'" .)
