Crossword Genius

He's a rotter around daughter (3)

Ross

I believe the answer is:

cad

'he's' is the definition.

'a rotter around daughter' is the wordplay.
'a rotter' becomes 'scab' (I've seen this in another clue).
'around' indicates the central letters.
'daughter' becomes 'd' (genealogical abbreviation).
The centre of 'scab' is 'ca'.
'ca'+'d'='CAD'

(Other definitions for cad that I've seen before include "Dishonourable man of decadent sort" , "Wretch" , "That ain't no gentleman" , "designing software" , "Ungentlemanly person" .)

I've seen this clue in The Sun.
