He rakes in shattered crags, even (9)

I believe the answer is:

scavenger

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

'he rakes' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'shattered crags even' is the wordplay.
'shattered' indicates anagramming the letters.
'crags'+'even'='cragseven'
'cragseven' with letters rearranged gives 'SCAVENGER'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for scavenger that I've seen before include "carrion-eater" , "sweeper" , "Garbage collector" , "Jackal" , "Carrion-feeder" .)

I've seen this clue in The Telegraph.
