His bank account is often misleading (6)
I believe the answer is:
angler
'his bank account is often misleading' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for angler that I've seen before include "A rod-and-line fisherman" , "Isaac Walton wrote of the 'Compleat' one" , "One proverbially exaggerating" , "He fishes with rod and line" , "Fisher with hook and line." .)
