Frank in Devon shows such benevolence (4-11)

I believe the answer is:

kind-heartedness

'such benevolence' is the definition.
The definition suggests a singular noun which matches the answer.

'frank in devon' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
This explanation may well be incorrect...

'shows' acts as a link.
