Miser finding strange geezer's robe once (8,7)
I believe the answer is:
ebenezer scrooge
'miser' is the definition.
(I know that Ebenezer Scrooge is a miser)
'strange geezer's robe once' is the wordplay.
'strange' indicates anagramming the letters.
'geezers'+'robe'+'once'='geezersrobeonce'
'geezersrobeonce' anagrammed gives 'EBENEZER SCROOGE'.
'finding' acts as a link.
(Other definitions for ebenezer scrooge that I've seen before include "mean-spirited miser" , "protagonist in 1a [A CHRISTMAS CAROL]" .)
