I wasn’t sure that the last clue was a very good one but I’m finding them hard to think up nowadays.
Anybody else can post one, of course.

I was a bit surprised at the number of guests.

Yes. You’re right, again, Courtenay.
The author H H Munro was known as Saki and a Munro is a Scottish Mountain which is at least 3,000 feet high.
Well done, again.

Author who is being sheltered inside, with arms akimbo - on a Scottish mountain? (4)

You’re right, Anjalli. Your turn next.

Thanks, Anjalli.

Next question.
In ‘In The Fifth At Malory Towers’, what is the name of the sewing mistress?

Very well done, Courtenay. You’re correct again.

A seat by a river, according to Enid Blyton. (7)

I agree with you, Bertie.

Likewise. I realised that the post had gone through.

I’ve not read this book for years but I think it was Gwendoline.

I didn’t bamboozle you for very long with that clue, Courtenay.
Well done.

Somehow blamed endless booze for being deceived. (10)

That’s the right answer, Bertie. Excellent.

Hi, Courtenay. You beat me to ‘NOBODY expects the Spanish Inquisition’. Well done.

Grand Inquisitor’s drama quote is nasty. (10)
