I found this difficult in places and finished it in a stop/start fashion.
Most of the clues seem quite reasonable except for 14, which left me cold. It seems to be a very weak CD but was completely unhelpful to me in ID’ing the answer. Otherwise, there were some quite nice devices on offer – the neat use of the two short words to clue 25 and lots of cunningly expressed containment indicators.

| Across | ||
| 1 | INSOMNIA | Inability to retire successfully when you’ve worked as minion (8) |
| (As minion)* | ||
| 5 | SCAMPI | Second course at meal starts with very good seafood (6) |
| Initial letters of “second course at meal” + pi | ||
| 10 | MATINEE | China cups in eastern show (7) |
| Mate around (cups) in E(astern) | ||
| 11 | ENDORSE | Fictional moon leading to extremes of space and back (7) |

| 25 | TOASTER | Kitchen appliance for when time’s short (7) |
| To(=for) + as(=when) + ter[m]. I’m never totally confident about the interchangeability of these short words, but they are so widely used there must be contexts where they have similar meanings. | ||

I wasn’t thrilled with 14a either – ended up OneLooking it. Otherwise top stuff.
Many thanks S&B both.
Not impressed with 14ac, nor with 15dn, both of which I biffed. But there were others I liked, including EAVESDROP and ASBESTOS. And I liked the misdirection in 26ac, suggesting that H (‘hotel opening’) would be the last letter (‘after’) of the answer – it took a while for the penny to drop.
Thanks, Lohengrin and HealH
It took a lot longer than usual, so an enjoyable challenge although I fell for the Spooner trick in 18ac and spent too long jumbling words before the penny dropped.
Reaction to 14ac was ‘Well I suppose so’
Thanks to S & B
Thanks, Neal.
I did mostly enjoy this but found the last few really hard to pin down. Another one who wasn’t keen on TROUBLESHOOT and I thought MYRMIDON was really obscure for a daily cryptic. And not that I give a crap, but I thought KATE was a duchess and not a princess?
Maybe not Lohengrin’s best so far, but he has set himself very high standards.
Yes some of this was extremely difficult. I ground to a halt and used aids to finish. Never heard of a neural computer. Didn’t like 14ac. But did like 15dn.
Thanks for the blog, comments and all.
I must apologise about 14ac, but to me, I would never read ‘ID problem’ as anything other than a problem with one’s ID, which in my head, made it a nice CD.
Lohengrin
With you on that, Lohengrin. That’s how I read it, and I thought the CD clever when I tumbled to it.
Thanks Rog,
Glad someone read it the right (wrong) way!
