As we prepare for another long “Downton Abbey” dry spell (the final Season 3 episode will air today), some of us will be looking for something Downton-ish to read. I sampled four current novels, all of which name-checked “Downton Abbey” on their covers. Alas, no character came close to the Dowager Countess, and in general there wasn’t nearly enough below-stairs scheming, but each offered pleasures of their own.
