The night before graduation, my sister called, her voice trembling. “Before your daughter gets home, check behind the living room painting.” I frowned. “Why?” Through tears, she whispered, “Because what’s hidden there… isn’t just dust.” My hands shook as I moved it—and the moment I saw what was behind it, my world stopped.

“Before your granddaughter gets back, look at what’s behind the painting in the living room.”

My sister Beth’s voice was trembling so much I almost didn’t recognize it. It was eight o’clock at night, and Sarah, my granddaughter, had gone out with her friends to finalize the details for her high school graduation party.

“What are you talking about, Beth? I just cleaned there this morning.” My heart started to beat faster. I recognized that broken, urgent tone in my sister’s voice. It was the same one from when we were kids and she had discovered something terrible.
