Finished Christmas at Candleshoe by Michael Innes. It was a special 99p offer on Audible's Advent Calendar but actually had nothing whatsoever to do with Christmas.
It's quite an enjoyable quirky little tale written and set, I think, in the late 1940s about two branches of an old titled family, a rich American widow, an orphan and the possibility of some hidden treasure. In places it reminded me of Peter Pan, there was also a hint of P. G. Wodehouse and maybe a bit of Famous Five thrown in too. No Christmas though.
For my final Christmas themed listen I'm going for Agatha Raisin and Kissing Christmas Goodbye by M. C. Beaton.
