I thought that I'd replied to this so apologies for that.
Something mysterious is fine with me and I'll try harder to be broader in future suggestions 😊
As for what I'll read, I don't know yet but I am leaning towards Agatha Christie and/or Arthur Conan Doyle.
Then again, I just bought the latest Sarah Pearse novel, The Wilds, which is a mystery. So I'll start with that, after I've finished Great Expectations.
