City map covering a new fraud (9)
I believe the answer is:
charlatan
'fraud' is the definition.
(I've seen this before)
'city map covering a new' is the wordplay.
'city' becomes 'LA' (Los Angeles).
'map' becomes 'chart' (synonyms).
'covering' indicates putting letters inside.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'la' placed inside 'chart' is 'charlat'.
'charlat'+'a'+'n'='CHARLATAN'
(Other definitions for charlatan that I've seen before include "Quack, fraud, a flamboyant deceiver" , "Impostor, deceiver" , "imposter" , "ake" , "Flamboyant deceiver, mountebank" .)
