Murder in the Hellfire Club — Donald Zochert

The Hellfire Club was a ribald fraternity of thirteen members. It was dedicated to lechery and lust--but it was not accustomed to death.... The porter at the Vulture Tavern has been found dead in a room locked from within. His corpse bears no trace of violence. In all London, only one man calls it murder--the visiting American and pioneer in electrical experiments, Benjamin Franklin. He believes he has uncovered the world's first murder by electricity. As more murders follow, Franklin sets out in pursuit of a diabolical killer. The trail will lead to blasphemies, debaucheries, desecrations--in short, to the lewd rites of the Hellfire Club!
