Thomas Maple lives on Crystal Palace Road with his niece Verity. He works for a firm of bank note engravers.
When Verity meets her new employer she develops serious misgivings, and arriving back home she can hear a menacing voice. "A Debt Discharged" is a novel about forged dollar bills and a young girls investigations into her suspicious new employer.
These were largely adventure narratives with elements of crime or mystery, and usually combined a bombastic sensationalism with hammy violence.
