The key opened a hidden safe in the master bedroom, and inside was proof of who had planned the whole thing, months in advance. As I read the last name written there in black ink, the floor seemed to drop out from under me.

Part 3

The name on the paper was Dr. Gregory Cárdenas — the Granger family’s trusted physician for years.

I’d known the man a long time, and trusted him completely with our family’s health. He’d been a guest at the wedding, had held Tanya as a baby, had eaten at our Christmas table more than once.

I’d told Katherine, more than once, that she could count on him in any emergency.

According to her letter, Gregory hadn’t only signed the false psychiatric diagnosis. He’d also written prescriptions for heavy sedatives in my daughter’s name, without her knowledge, and delivered boxes of them straight to Heather.
