I started digging. I remembered Karen’s best friend, Linda, who had always been strangely supportive of me. I called her. After some hesitation, she admitted the truth. Karen was desperate for money. She owed $200,000 to a loan shark named Vinny. She had hoped that if Sarah divorced me, Sarah would inherit the lottery money and share it with her mother. Linda had been helping Karen plan the accusation. She felt guilty but was too scared to come forward.
