When Eileen spotted the letter on the windowsill, she thought it was something innocent. But when she opened it, her hands shook as she read.
She knew she had to go. If she delayed, or brought other people with her, Sal was capable of killing. Grabbing her whip, she quietly went to the front door and opened it, stepping outside.
[OOC: I kind of figured Sal would include language indicating she needed to come alone, and also it makes Eileen look less foolhardy. I hope that's not a mistake.]
