Five solutions are wordplay only
Answers to clues are modified so crossers won't help...
10a Detailed look at women's mag's horny beasts (8) assume ends in OKS (antelopes?)
2d Left in the lead...(4)
3d....second best (4)
17d Couldn't imagine John Glenn's chief was in charge (7) ????GIC
10. It doesn't end OKS. It's a 'look' ('detailed' leading to the usual crossword convention + the name of a woman's mag (possessive). This gives you horny beast.
17 The definition is 'couldn't imagine'. The John is a slang/colloquial word for …+Glenn's chief , the usual convention + 'was in charge', ran etc. Your letters aren't correct.
Mallyh, it probably looks, sounds, more complicated than it actually was. I was trying not to give direct answers as the crossword only came out on Monday and there's almost a month to go until the closing date.
Thanks ....but not really any wiser....saw the help given on the other site and couldn't fathom it, so asked here.....never mind i'll leave it for a while
