Crossword Genius

Deceive prisoner (3)

Ross

I believe the answer is:

con

This clue is a double definition.

'deceive' is the first definition.
(I've seen this before)

'prisoner' is the second definition.
(abbreviation for 'convict')

(Other definitions for con that I've seen before include "Deceive; prisoner" , "Learn; swindle" , "Dupe" , "Trick, deceive" , "Prisoner (sl.)" .)

I've seen this clue in The Times and The Mirror.
