Dickensian kid (6)
I believe the answer is:
oliver
'dickensian kid' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oliver that I've seen before include "Musical (with a Twist!)" , "Dickens boy named Twist" , "Dickensian role?" , "Dickensian musical" , "stage show" .)
