Lady Marblehead is not pleased. In fact, she's furious. Not only is someone trying to poison her, but the impertinent scoundrel is after her jewels too.

All the clues seem to point to her new doctor, a young Jewish man recently arrived in London. But is he really the one responsible? Or is there some darker, more malevolent force at work?

In this first book in the Jewish Regency Mystery Series, it's up to wealthy-widower-turned-sleuth Mr. Ezra Melamed to find the culprit - before the poisoner strikes again.
