Bill and Edward crossing Greek island will get waylaid (8)
I believe the answer is:
accosted
'waylaid' is the definition.
(I've seen this before)
'bill and edward crossing greek island' is the wordplay.
'bill' becomes 'act' (I've seen this in other clues**).
'and' is a charade indicator (letters next to each other).
'edward' becomes 'ed'.
'crossing' is an insertion indicator.
'greek island' becomes 'cos' (I've seen this before).
'act'+'ed'='acted'
'acted' enclosing 'cos' is 'ACCOSTED'.
'will get' is the link.
(Other definitions for accosted that I've seen before include "Waylaid" , "held up" , "Approached and spoke to" , "Approached and addressed boldly" , "Approached boldly and aggressively" .)
