I'm a little stuck... Click here to teach me more about this clue!

'inspector's' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?

'wife visiting stormy isle' is the wordplay.
'wife' becomes 'w' (abbreviation).
'visiting' indicates putting letters inside.
'stormy' is an anagram indicator (stormy suggests disruption).
'isle' with letters rearranged gives 'leis'.
'w' inserted within 'leis' is 'LEWIS'.

Can you help me to learn more?
