Buchan's novel translation of Ten Large Men (11)

I believe the answer is:

greenmantle

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

'buchan's novel translation' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'of ten large men' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'ten'+'large'+'men'='tenlargemen'
'tenlargemen' is an anagram of 'GREENMANTLE'.

Can you help me to learn more?

(Another definition for greenmantle that I've seen is " LITERATURE".)
