Once I got settled in the guest room, I read every text at least a dozen times. Like a masochist, I zoomed in on every picture, memorized every detail. When I ran out of material, I called the head of Prism IT at five in the morning and requested a record of every text or call Rob had ever made from his work phone. I did the same with our personal cell phone provider as soon as their offices opened, but my search didn’t end there.
