When Big Boy sent his subordinate "Confidence" Dolan to collect $10,000 in cash from Spaldoni (which Big Boy planned to use to flee the country), Spaldoni arranged for his confederates to steal the money from Dolan.
Knowing there was jealousy between Jean and Tess Trueheart, Spaldoni forged letters filled with invective and sent them to the two women in order to increase the rift between them. He then lifted Tess' fingerprints and planted them on the handle of a gun.
When the two women had a fight, Spaldoni shot Jean and planted the gun where it would implicate Tess. Tess was arrested, but Spaldoni realized that Dick Tracy could match the handwriting on the fake letters with the letter he had given Jean when she had bailed Jimmy White out of jail.
Tracy made the connection before Spaldoni could prevent it, so Spaldoni and his gang fled to an abandoned steel mill where a shoot-out ensued. Tracy narrowly avoided being buried alive by scrap iron in a death-trap triggered by Spaldoni (May 1, 1934). Spaldoni's gang were killed and Spaldoni was fatally injured. On his death bed, he confessed to the crime, exonerating Tess.
Following his death, Spaldoni's past was revealed to Tracy by Spaldoni's mother Edith. She informed the detective that Spaldoni's real name was George Bumpsted and that he had been born in London, England. His father had passed away when George was 12 years old. The black sheep of the family, Spaldoni had taken a new name to distance himself from his mother and brother, a famous European police officer. Spaldoni's brother would soon become embroiled in Dick Tracy's next adventure.
