Excerpt: ""Hello! hello! This is Frank Mantell talking. I want Mr. Carter—Nick Carter. Is he there?" Patsy Garvan, the detective's junior assistant, then alone in the library of Nick's Madison Avenue residence, was the recipient of the above telephone communication. It came over the wire in tones reflecting the haste and excitement of the speaker. Patsy remembered him, a son of the senior partner of the firm of Mantell & Goulard, whose big department store in Sixth Avenue had recently been wrecked by a long series of mysterious robberies committed by the junior partner, Gaston Goulard, resulting in a round-up of the criminal and his confederates by Nick and his assistants, all of which had transpired several months before."
