monster 116

How many letters does it have, and what have you already got?

h?n????e?t

Unfortunately l have already sent mine off, so cannot remember what l put for this clue, but on checking google etc., l only come up with OPEN DOOR, so not sure how this would fit into your grid, but good luck hope you find the answer.

How sure are you about the H at the start?
Any chance it could be CONVENIENT?

many thanks cherrie
