While they hunted, small things changed. Arjun's neighbor started humming a lullaby he could not place. Maya found a grocery receipt in her jacket pocket with items she hadn't purchased. Karim posted, briefly, a thread warning people to avoid "vegafiles." The thread had a single reply: "We are already inside your viewing."
"You made this," Maya said. "Who are you?"
A breakthrough came from a source they hadn't expected: the Director's original crew logs, posted anonymously on a fringe board by someone who signed only as "E." The posts were raw, angry, written in the shaky hand of someone who had watched colleagues alter each other's memories until relationships frayed. "We were told we were creating honest art," E wrote. "We were told the Shift would be theory, a trick. It wasn't. It was a door." Attached to the post were coordinates to a warehouse on the city's edge and a plea: "Burn the drives."
