Thanks everyone, all done now - really appreciate everyone's help today. Hope you're all enjoying the long holiday weekend - isn't it great that we don't have to go to work tomorrow! Cheers again, Chox.

Excuse the piggybacking. Got all these OK, but stuck on 20 ac: Calm people agree (6) -e-t-e. Looks like SETTLE, but can't really parse that satisfactorily. Thanks.

[scorpiojo]

Double definition - calm & people agree

[Mamyalynne]

Triple

calm/(to) people/agree

[scorpiojo]

..possibly triple as in 'to stock with people'

[Cryptomaniac]

Thanks all. Just a double meaning I think.
