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 judge whether it can be defined by this definition.

'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".)
