Perhaps the dirt she was living quote was not in reference to actual dirt, but was a veiled reference to the years of the case, the vicious rumours, the instability of her life (not mental). After years of living this battle since 1926, which was almost 60 years, she could very well be referring to the case, in all it's various aspects and the notariety it brought to her. Surely at that point after having the longest running court case in history, testimonies, affadavits, name calling, aspersions, threats, it ALL could have been dirt to her.
