Perpetual?

4 Douane

What is the clue for 22a ?

[novalis]

I think perpetual as well but 4 across is houses ( ho-uses )

[French solve]

Thanks to all. Sorry I forgot the clue to 22 across, it's"Like a sort of check on patterned board" Perpetual fits fine, but I'm not sure how it answers the clue.
For 4 across, I think it must be "houses".
Thanks again, I found it hard today.

[novalis]

In chess there is a position known as perpetual check.
