One of those working with Fagin - a type of fence getting to grips with policeman setting up extreme kleptomaniac
I believe the answer is:
pickpocket
'up extreme kleptomaniac' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'one of those working with fagin a type of fence getting to grips with policeman' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'of' could be 'o' and 'o' is found in the answer.
'policeman' could be 'pc' and 'pc' is present in the remaining letters.
This may be the basis of clue (or it may be nonsense).
'setting' is the link.
Can you help me to learn more?
(Other definitions for pickpocket that I've seen before include "Tea leaf" , "Artful Dodger?" , "Dip" , "Thief working in public places" , "Cutpurse" .)
