Margaret Gives Nucky's Land Away to the Church (Season Two, Episode 12)
Margaret's decision to shack up with Nucky back in Season One was both contemptible and understandable. He was responsible for the death of her abusive husband, yet he provided comfort and security for Margaret and her children during a time when women had limited options. But Margaret's pact with the devil continued to weigh heavily on her conscience even as she reaped the benefits of her newfound wealth and power. When her daughter, Emily, was stricken with polio, Margaret saw it as a punishment for her sinful ways. Desperate to settle her debt with God, Margaret – Nucky's wife at this point – signs over the deed to a large portion of land her husband had given to her for safekeeping during his election-fraud scandal to St. Finbar's Church. Her decision effectively ruins Nucky's intended lucrative deal for additional roads to Atlantic City – and, most likely, her brand-new marriage.
