The email arrived at 2:17 a.m. No name. No signature. Just one sentence in the subject line: “Are you ready to write the truth?” I almost deleted it. I was a ghostwriter, and mysterious clients weren't unusual, but something about this email felt different. Maybe it was the payment offered. Ten times my usual rate. Maybe it was the attachment. A document titled simply, “Chapter One.” I opened it. The first line read: “On the night of October 17th, I will kill her.” I stared at the screen. Then I closed the document. I deleted the email. I went to bed. At 8:03 the next morning, the email was back. Same subject.
