Thanks,Neveracrossword. That tells me 10 across was not maryolater, but can’t as yet replace it - but no luck in Brewer for 33d, nor in ‘mysterious lost ships’ via Google.
Neveracrossword - thanks for constant help - I was using an old Brewer that was handy, but now consulting my Millennium (previous Speccie Xmas Prize!) and found 33d. (I could not get an answer slot to yr last, so came back.) Still lost about 4th letter in 4d - only thing missing and I swear not in Brewer!
