As the city of Minneapolis prepares for a visit from President William McKinley, someone else prepares for murder. On the day before the visit, a union activist is found hanged, naked, outside a ruined mansion. A placard around his neck reads 'THE SECRET ALLIANCE HAS SPOKEN'. Who is the alliance? What does it want? How was the victim involved with the citys corrupt mayor? And why did he possess a photograph of a prominent citizen in a compromising position? Shadwell Rafferty searches for answers, encountering bribery, corruption, union organizers, anarchists, and conspiracy, putting himself in danger. But as luck would have it, his old friends Sherlock Holmes and Dr. John H. Watson are on their way.
