**A puzzling note from a troubled woman draws an American expat author into the lawless precincts of Victorian London in this historical mystery.** *London, 1901*. Denton, the notorious American writer, has returned to his adoptive home after several months in one of the less-delightful corners of the Continent. He’s greeted by the usual letters from fans craving more tales of adventure—and one peculiar note: “I believe that someone threatens to harm me, and I do not know quite what to do.” Though it is signed “Mary Thomason,” it was sent by someone else. And it is more than two months old. Much as he’d like to deny it, Denton is a Victorian gentlemen to the marrow. And he cannot deny a damsel in distress. His search for the mysterious Miss Thomason will take him deep into London’s “bohemian” quarters—as well as the darker corners of his own soul. “Other authors have set mysteries in the same period and place, but Cameron stands out by virtue of his fine plotting and distinctive characters.” — *Publishers Weekly*
