Thomas Maple lives on Crystal Palace Road with his niece Verity. He works for a firm of bank note engravers. However, the dollar bills he shows Wentworth Gold are forgeries - perfect except for the missing Treasury sign. When Verity meets her new employer she develops serious misgivings, and arriving back home she can hear a menacing voice. What power do these men hold over her uncle? Who is the mysterious he? She hesitates, then follows them.
