Yank with new perfume, leaving Charlie particularly fortunate (6-4)

I believe the answer is:

heaven-sent

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

'particularly fortunate' is the definition.
(something heaven-sent is very fortunate)

'yank with new perfume leaving' is the wordplay.
'yank' becomes 'heave'.
'with' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'perfume leaving' becomes 'sent' (I can't justify this - if you can you should give a lot more credence to this answer).
'heave'+'n'+'sent'='HEAVEN-SENT'

'charlie' is the link.
I am not very happy about this link. It may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for heaven-sent that I've seen before include "Occurring just at the right time" , "Coming at a very opportune time" , "Providential" , "Very timely" .)
