The Tls arrives late here in France so I'm still on Tls 1371. Just got it today. The only one I can't do is 1 down. The "cheesy device" looks as if it should be a "grater" but I can't parse it. Not an anagram of "target". I'm baffled. Can someone explain? Thanks.
Perhaps so, aelmppvw. The clue itself seems to be "off-target". Maybe that's what the setter was driving at! I think I'll just leave it blank. Thanks everybody for your help.
