Shifty fellow (6)
I believe the answer is:
dodger
'shifty fellow' 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?
This is all the clue.
Can you help me to learn more?
(Other definitions for dodger that I've seen before include "Oliver is the artful one" , "Dickens created an Artful . . . . . ." , "Roger, possibly" , "The Artful . . . . . . was Oliver Twist's friend" , "Artful Dickens character" .)
