After the assassination of U.S. President McKinley in Buffalo, Ottawa-based spy Terrence Meyers shows in Toronto. The Canadian government is concerned that some of the assassin's co-conspirators may try to make their way to Canada to avoid U.S. authorities. Rumors have it that Emma Goldman is back in Toronto and the police begin rounding up anyone who might be considered the least bit subversive. Among them is Anton Woycek who is later found dead in a warehouse with Meyers standing by him with the gun in his hand. That's enough for the supremely arrogant American spy Allen Clegg who believes Meyers is part of the conspiracy. Murdoch sets out to prove Meyers' innocence and find out exactly what is going on.
- The assassination of the President of the United States was foreshadowed at the end of War on Terror in Season 5, which also included Meyers, Clegg and Emma Goldman.
- At the end of the episode, George hands William a note from Julia. He meets her in a shadowy back alley where upon Julia tells him that Gillies is still alive and has been sending her death threats.
- President McKinley's assassination by a man claiming to be an anarchist in Buffalo, New York.
- Maureen Jennings once named the novel "The Spy Who Came in from the Cold" as one of her favorite books. This episode title is allusion to that book, and also works as the spy Allen Clegg comes up to Canada (the Cold).
- The actress Melanie Leishman first appeared in Downstairs, Upstairs (ep.404) as Nancy Booth. (see Recasted Actors).
- Julia to William: "Life without you, William, is worse than death."
- William to Julia: "Together, we are stronger than anyone."
