My 4-year-old daughter died from a severe allergic reaction at daycare. Everyone called it a tragic accident—until her teacher called me at 2 A.M. “Your husband hasn’t told you the truth,” she whispered. Then she sent me a video. As I watched my husband on the screen, I realized the nightmare had only just begun…

He wanted me sedated. He wanted me docile. He wanted me unconscious so he could finalize his plans.

But I wasn’t swallowing them. Every night, I palmed the heavy sedatives, pretending to wash them down with water, before secretly flushing them down the master bathroom toilet. Because when Mark fell asleep, when his deep, even breathing signaled that his sociopathic mind was at rest, I went to work.
