On the night of Mr. Melvyn's murder, Elaine was getting real tired of Knickers calling her & breathing down the phone.    It had gotten to a point where she'd considered telling Moe, who also worked at the medicinalplant on the outskirts of town, to take care of it.    Not that that would probably help much - he was great for giving her rides back from work, but she needed a real man to take care of Manny. Not some scrawny unheathy-looking geek.
