The Bradys and the Girl Smuggler; Or, Working for the Custom House

Two Secret Service detectives, an experienced elder and his energetic young partner, are hired by the Custom House to stop an ingenious diamond-smuggling operation. Working undercover among importers and jewelers, they gather clues, pose as boarding officers, and accept a public challenge from skeptical inspectors. Their investigation leads them to a stylish foreign dealer and his daughter, prompting pursuits and confrontations on ships, in buildings, and across the city. Through disguises, daring arrests, interrogation, and careful sleuthing they recover the contraband, unmask the ring, and secure the smugglers, emphasizing procedural craft, clever tactics, and the tension between official and independent investigators.
