For example, Sikes’s account? (4)
I believe the answer is:
bill
I believe this is a double definition.
'for example sikes's' is the first definition.
(Bill Sikes from Oliver Twist is an example)
'account?' is the second definition.
(billing is a kind of accounting)
(Other definitions for bill that I've seen before include "beak demanded" , "following 28 [SILVER]" , "Poster; statement" , "Narrow promontory" , "amount owed" .)
