"Sherlock races downstairs, his heart pounding at each step he takes. He dreads each second-each precious second- the life threatening seconds he knows too well. Nearing the steps, he hears a gunshot."
After John is shot by a sniper in The Reichenbach Fall, Sherlock has to live without him, but he meets a traveler, two brothers, and an angel, who help him get John back.
