We saw a documentary on the Cold War, in which people suspected that certain suicides were actually a cover-up for murders. One of the ways these murders were supposed to have been done was by knocking the victim out on the edge of a window and then throwing them out of it. We also recalled the suicide in the summer of 2010 of a patient in a Montreal hospital, who jumped from a ninth-floor window. We put these two unrelated anecdotes together to write our story.
