Dickens novel involving Mr Bumble and Bill Sikes (6,5)
I believe the answer is:
oliver twist
'dickens novel' is the definition.
(Charles Dickens novel)
'mr bumble and bill sikes' is the wordplay.
I cannot quite understand how this works, but
'mr' could be 'oliver' and 'oliver' is present in the answer.
The remaining letters 'twist' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'involving' acts as a link.
Can you help me to learn more?
(Other definitions for oliver twist that I've seen before include "Dickens character who asked for more" , "Dickens' novel" , "One wanting more" , "Dickens eponymous hero" , "Eponymous Dickensian character" .)
