Crossword Genius

Mister, a dude, contrived to get something much wanted (11)

Ross

I believe the answer is:

desideratum

'something much wanted' is the definition.
(I've seen this before)

'mister a dude contrived' is the wordplay.
'contrived' indicates anagramming the letters.
'mister'+'a'+'dude'='misteradude'
'misteradude' anagrammed gives 'DESIDERATUM'.

'to get' is the link.

(Other definitions for desideratum that I've seen before include "Something much wanted" , "As requirement" , "Something needed or wanted" , "Something much needed" , "Essential" .)

I've seen this clue in The Telegraph.
