Across
1 Steel, for example, and half of that gold-plated?
AUTHOR
Cleverly constructed clue to get us going (or those of us who always start with 1 across, at least). An insertion of TH[AT] in AU and OR, two abbreviations for ‘gold’, so ‘gold-plated’ as the insertion indicator. The author is Danielle Steel. She is the bestselling living author and the fourth-best-selling fiction author of all time.
4 People who dole out corporal punishment and kisses
SMACKERS
A dd.
10 Notoriously thirsty thespian drinking gallons in lake showed up again
RE-EMERGED
A double insertion: of G in MERE, and all that in REED. The two insertion indicators are ‘drinking’ and ‘in’. The ‘thespian’ is Oliver REED. He was certainly reputed as a heavy drinker: he claimed to have drunk 106 pints of beer on a two-day binge before his wedding day. This turned out not to be entirely true: he drank 106 pints during an arm-wrestling competition in Guernsey fifteen years prior to his wedding.
11 Straighter French street runs through outskirts of Tréguier
TRUER
An insertion of RUE in TR, the outer letters of ‘Tréguier’. The insertion indicator is ‘runs through’.

A dd. The second definition is more clearly rendered by RE-SIN.

An insertion of DENT in EVIL, followed by Y for the NATO/phonetic alphabet ‘Yankee’. The insertion indicator is ‘into’.

Hubble is inviting you to create CEA by moving the ‘head’ of ACE for ‘expert’ downwards, and insert it in ON for ‘dealing with’. The insertion indicator is ‘getting stuck into’. Neptune is the Roman god of the sea.
5 When youth has gone, warehouse’s initially replacing learner who helps with deliveries
MIDWIFE
A replacement of the L in MIDLIFE with W for the initial letter of ‘warehouse’. MIDWIFE has an interesting etymology: it’s formed from the two Middle English words mid, ‘with’, and wif , ‘woman’, which gives it its modern meaning of a ‘woman who is with’ (the mother at birth).

Many thanks to Hubble for this Monday’s puzzle.

Just heard a book show on the radio that said August is romance month, but never heard of Danielle Steel — surprising. Not my genre, but still, with 200 books and a billion copies in 40 odd languages … (talk about gold-plated!).
Anyway, nice puzzle, thanks Hubble and Pierre.
Agree with ‘solid and entertaining’. AUTHOR my favourite and loi but like #1 GiF, a ‘never heard of’. Liked the clue. Also liked OCEAN and MIDWIFE. IDIOM could not have been anything else but I failed to parse it. A tad corny, imho. Thanks Pierre and Hubble.
(* Typo in 28A, should be GI’S not just GI it seems)
Once again a rare moment where I finished a crossword though there are still new things I learned and only got after the fact: Danielle Steel (even though she is that famous), Oliver Reed, and orbit meaning “sphere of influence”. I think I’ve seen IOM before except I don’t remember where.
Some clues I appreciate: 13A (conciseness), 14A (this took me a while to realize but alien visitors = UFOS is nice), 16A (surface), 5D (surface; delivery of a baby was not my first guess for the meaning), 21D (conciseness), and 25D (surface and simplicity).
(EDIT: Honorable mention for me goes to 1A with the creativity of the cluing, though it took me a while to get that TH should be plated with two golds, not just one.)
Thanks Hubble and Pierre!
I thought AUTHOR was excellent – I have never read a word of the lady’s oeuvre but I have certainly seen her works. COURTROOM and OCEAN make up my podium.
Thanks both
AUTHOR, AIRCRAFT, OCEAN and SOMETIMES.
Thanks Hubble and Pierre!.
Ironically, given the name of the setter, I didn’t need any aids to see the answers. AUTHOR and SOMETIMES were my favourites.
