Dickens character arresting one more suspect (7)
I believe the answer is:
dodgier
'more suspect' is the definition.
Both the answer and definition are comparative adjectives. Perhaps you can see an association between them that I don't see?
'dickens character arresting one' is the wordplay.
I cannot quite see how this works, but
'character' could be 'r' and 'r' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
The remaining letters 'dodge' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for dodgier that I've seen is " Less reliable".)
