Hannah took a deep breath. In her memory, Robert always came home early to be with Brianna, or he took her out for candlelit dinners. Their love had lasted over a decade, but since that lipstick mark appeared, her father had been coming home late every night, never before eleven.
"Mom, shouldn't you act quickly? Get rid of the mistress before she becomes a real threat!" Hannah said fiercely.
Brianna sneered. "There are no suspicious women around your father yet, but he won't stay that way for long."
"Mom, are you saying... Dad is cautious of you?"
"Of course. After so many years together, he knows me well. There was a time he cheated before, and I got rid of that mistress quietly. But over the years, he has started to suspect me."
