The Vanisher Variations — Libi Astaire

There's trouble afoot in Regency London's Jewish community, and no one to stop the crimes -- until wealthy-widower-turned-sleuth Mr. Ezra Melamed teams up with an unlikely pair: General Well'ngone and the Earl of Gravel Lane, the leaders of a gang of young Jewish pickpockets. In this fourth volume of the Jewish Regency Mystery Series, General Well'ngone and the Earl of Gravel Lane are dispatched to Brighton to watch over the wife of a Junior Lord of the Treasury, who has received a message threatening her life. When the lady vanishes while visiting Mahomed's Steam and Vapour Sea Water Medicated Baths, accusations fly and chaos ensues -- and to find the lady Mr. Melamed must battle wits with one of the craftiest criminal minds in England.
