Nicholas and Edward get arrested (6)
I believe the answer is:
nicked
'arrested' is the definition.
(I've seen this before)
'nicholas and edward' is the wordplay.
'nicholas' becomes 'nick' (Nick is short for Nicholas).
'and' means one lot of letters go next to another.
'edward' becomes 'Ed' (short for Edward).
'nick'+'ed'='NICKED'
'get' is the link.
(Other definitions for nicked that I've seen before include "Stolen -- arrested" , "Put small dent in, or slangily stole" , "Cut slightly, with a razor, say" , "Pinched and made a notch" , "Slangily stole, or made small dent in" .)
