Not quite as easy as some recent puzzles in this series, but all clear in the end.
Solving time: 21 mins
ACROSS
1 GE(R)T RUDE R = King Queen Gertrude of Denmark, mother of Hamlet in Shakepeare’s play.
8 SLAVER(y)
10 BEA(G)LE g (good) for d (daughter) in beadle (“parish officer”) as the setter as editor of the Church Times Crossword will know well, I’m sure.
12 BRON (born)* CO “care of” Good. Definition and wordplay side by side, but whole clue can read as a definition too. “Horse born to be wild that’s taken care of” “that’s taken” is a link in the wordplay.
14 LIMP E T
17 B LOND(on) E Harlow in Essex and (Jean) Harlow (1901-1937) the blonde.
20 CHAR LOCK My last entry. Wild mustard.
DOWN
1 HELIUM He is its chemical symbol. Clever, and, though I’d seen this idea before, for this element and others (e.g. As = Arsenic), did not get it for quite a while.
3 CUTTING CORNERS Do an empirical test with any square or rectangle – take the corners off and you’ve an eight-sided figure.
5 MA (LAPROP) (popular)* less u. Mrs Malaprop, someone who misuses words, originally from a character in Sheridan’s play “The Rivals”. Related noun: malapropism.
6 BELL TENT (tell)* in bent = a type of grass
8 SEBASTIAN CABOT Venetian navigator and cartographer (1474-1557) (AB cast into sea b)* – Good surface reading. AB, a crossword staple from way back meaning able-bodied seaman (or seawoman) – one more skilled than the ordinary seaman (OS). Here, of course it’s part of the “anagram fodder”
12 BOATLOAD Jolly = sailor (a royal marine). Good
18 ECCLES A town in the Salford area and also abbreviation of Ecclesiastes (Book of the Bible), not Ecclesiasticus, as I had thought – thanks to Quixote himself (see below) for putting me right on this. Took me a while to get this answer.
Ecclesiastes, actually
Won’t argue with the editor of the Church Times xword on this – he is correct. The book I erroneously quoted is one of the Apocrypha (which must have been lodged in memory)
