Reading progress update: I've read 100%.

An English Murder - Cyril Hare

This was fun. My hunch about the solution was not entirely wrong but wrong all the same. I loved the William Pitt clue but the real solution was so much better than what I had thought of.

 

And if this could not have gone better, I believe the book qualifies for the Door 17 Winter Solstice task as there is snow on the cover.
