Cheat caught by Interpol finally, is he wrongly being imprisoned? (6)
I believe the answer is:
chisel
'cheat' is the definition.
(I've seen this before)
'caught by interpol finally is he wrongly being imprisoned?' is the wordplay.
'caught' becomes 'c' (cricket abbreviation**).
'by' is a charade indicator (letters next to each other).
'finally' suggests the final letters.
'wrongly' indicates an anagram.
'being imprisoned?' indicates putting letters inside.
The final letter of 'interpol' is 'l'.
'is'+'he'='ishe'
'ishe' with letters rearranged gives 'hise'.
'c'+'l'='cl'
'cl' going around 'hise' is 'CHISEL'.
(Other definitions for chisel that I've seen before include "Cutting tool for shaping wood or stone" , "Wood-shaping tool" , "Flat steel tool with a cutting edge" , "Wood, stone or metal-cutting tool" , "Slangily cheat with wood-working tool" .)
