Released from the Secret Service in 1912, Wiggins sails for New York to find his lost lover, Bela. But after an altercation onboard, he finds himself in Dublin, where he falls in with gangster Patrick O'Connell and is soon driving the boss's girlfriend Molly around town. She wants O'Connell to support the Irish nationalists—a cause needing guns to defeat the British—and they head to America to find them. In this third book in the series (after The Red Ribbon), Wiggins not only gets his chance to solve the mystery of Bela, he also crosses paths with his old mentor, Sherlock Holmes.
