A night-shift janitor is found hanged on Ellis Island and the apparent suicide is quickly ruled a homicide. The killer left behind an antique compass as a clue. Later, another compass mailed to Mac points to another murder victim on the opposite end of the city. Mac hires Haylen to work in the lab, much to Adam's dismay.
