Didn't lose the head with what aristocrat did to get away from Madame La Guillotine (5,3'1,4) (5,4,4)

'madame la guillotine 53'14' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'didn't lose the head with what aristocrat did to get away' is the wordplay.
I cannot quite understand how this works, but
'aristocrat' could be 'don' (I have seen 'Spanish aristocrat ' mean 'don' so perhaps 'aristocrat' could also mean 'don') and 'don' is found in the answer.
'away' could be 'a' (abbreviation as used in sports fixtures) and 'a' is located in the answer.
This explanation may well be incorrect...

'from' is the link.

Can you help me to learn more?
