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

'scrooge's passion' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'to find the origins of sin?' is the wordplay.
I cannot quite see how this works, but
'to' is present in the answer.
'of' could be 'o' and 'o' is found in the answer.
'sin?' could be 'fall' (fall is a kind of sin) and 'fall' is found in the answer.
This explanation may well be incorrect...
