Fruit pie – the last – it’s his (7)
I believe the answer is:
cobbler
This clue might be a double definition.
'fruit pie' is the first definition.
(type of US dessert)
'last it's his' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'the' is the link.
Can you help me to learn more?
(Other definitions for cobbler that I've seen before include "one at last found!" , "Shoemaker and repairer" , "An iced drink; a mender" , "One might fix heels" , "one getting down to work at last?" .)
