Quick recap
Washington, D.C., 1999. Geoffrey Shafer is a wealthy British diplomat with diplomatic immunity who feels he's losing control. His outlet is a fantasy game, the Four Horsemen, where he plays Death and kills for real while swapping emails with the other players. Bodies start turning up around the city, and Cross senses a pattern. Meanwhile, his personal life finally seems to settle down with Christine Johnson, until she disappears. Shafer's immunity makes reaching him as hard as arresting him. We found no reliable source for the ending, so it stays out.
