Thank you.
I looked them up and they're mysteries, which aren't my favorites, but I'll consider them anyway.
Try them out. In most of them, the mystery does not have to get in the way of what can also be read as a comedy of manners. They are not equally good, which is why we made recommendations. Gaudy night, in particular, can also be read as a thoughtful novel about gender equality in 1930s Oxford university. No one even gets killed in that one! But it is hard to understand without the back story of Strong Poison.
