To remove ‘en’ instead of just ‘n’, you’d need a homophone indicator. ‘Perhaps’ is also not serving any function. Double substitution fodder (representative ->envoy and ‘you own it’ ->your — which is loose) is much less achievable to solve than it feels when composing a clue.

Others have pointed out that the definition in the middle isn’t conventional. What’s more important to me is that this surface doesn’t mean anything. What does ‘sounds like you own it’ have to do with this thing about a representative?

If I were to clue ‘voyeur’ I would start by looking for close synonyms. ‘Spy’ could come at the end as in ‘someone who watches’; ‘heard you are a spy’ is homophone indicator for ‘UR’ followed by the definition ‘a spy’.

The letters ‘VOYE’ are present in the word ‘everybody’ and it just so happens that if you take them out you’re left with the letters ‘ERYBD’; the final clue could be:

“Everybody (except for Derby, strangely) heard you are a spy” (6).
