Eileen, Sondra and Janna, "The Three Crones", took every opportunity to defame him. They were why Meredith had left him. The spiteful bitches refused to stop meddling.
She'd told him, though she admired his diligence working so much, she needed a man who was around more. He raged that shows, dinners and such weren't free, so he WORKED for HER!! Nevertheless, the next day she was gone.
That night, The Three Crones each met their death at his hands. A short drive across town tomorrow, and Meredith would get HER just desserts. After all, he sneered, he WAS a diligent man.
