It's worth a hundred cents to escape from Monsieur Obrecht (4)
I believe the answer is:
euro
'it's worth a hundred cents' is the definition.
(there are 100 cents in a euro)
'to escape from monsieur obrecht' is the wordplay.
'to escape from' says the answer is hidden in the clue.
'EURO' is hidden within 'monsieur obrecht'.
(Other definitions for euro that I've seen before include "The Vatican's currency" , "Vatican currency" , "France's unit of currency" , "EU money" , "Multi-national currency" .)
