What Hepburn called Tracy (6)
I believe the answer is:
spence
'what hepburn called tracy' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for spence that I've seen before include "larder" , "Basil perhaps" , "Sir Basil ___ , British architect, d. 1976" , "Sir Basil --, architect of Coventry cathedral" .)
