"Seeking the Shadow" was published in the anthology Blackguards: Tales of Assassins, Mercenaries, and Rogues.
About this story, author Joseph R. Lallo says, "In the Book of Deacon's setting, the Northern Alliance and its southern neighbor, Tressor, have been at war for generations. Almost since the war began an assassin has stalked the northern lands, quickly becoming a legend among the people for both its skill and its elusiveness. This story takes place between The Book of Deacon and its prequel, The Rise of the Red Shadow. It is the much-requested telling of how two of the most infamous figures in the setting first crossed paths."
