Harry is sensitive in covering Queen's curiosity (15)

'curiosity' is the definition.
(inquisitiveness is a kind of curiosity)

'harry is sensitive in covering queen's' is the wordplay.
I cannot really see how this works, but
'is' is present in the answer.
an anagram of 'sensitive' is 'itiveness' which is within the answer.
'in' is within the answer.
'queen' could be 'qu' (abbreviation for queen) and 'qu' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
