"Here is what Nick told her: Walker had a Tumblr called "Photos of Sara. She doesn't know me," which featured nothing but photos and videos of Merker. That was strange enough. Walker had a girlfriend and didn't seem particularly interested in Merker, romantically or otherwise. But that wasn't even the strangest part: Merker hadn't posed for these pictures. She had never seen any of them before. In fact, she hadn't known any of the pictures were being taken. Michael Walker had a Tumblr consisting entirely of photos and videos he had secretly taken of Sara Merker." - × × ×
