The Second Woman: 3 (Denton) by Cameron, Kenneth | Paperback | Historical Mysteries

An American sleuth in Victorian London investigates the murder of a young Jewish woman in this "complex and gripping period whodunit" (Publishers Weekly).
London, 1901. With the Boer War raging, England's air is crackling with political intrigue. The rumors are so thick that the newly formed British Secret Service can barely keep a lid on. But it's not South Africa that is on everyone's lips. Rather, it's The Jewish Question: The armies of Antisemitism are on the march, even as the call to Zionism echoes through London's East End.
Denton, the famous American expat author, prefers to keep the conflict at arm's length—until his neighbor's murder brings it home. He could stay out of it. He should stay out of it. But . . . but he rather liked the woman. And the police are clueless. So Denton yet again sticks his pointy American nose into England's business. And he keeps it there, even as the price for asking questions gets perilously high.
