When a young boy, Alwyn Jones, reports seeing a giant shiny knight in the woods, Inspector Murdoch takes an interest and walks the boy home. There, he meets Alwyn's very attractive - and widowed - mother Enid. He doesn't have much time with her however since he's called away to investigate a murder.
The victim is Professor Ezra Dolomore, a mathematician who now works for a major industrialist. Dr. Ogden confirms that the man was poisoned and the fatal dose was administered in a unique way. When young Alwyn disappears, they find a dwarf floating in the river while looking for him, also poisoned.
Also involved in the case is the very secretive government agent Terrence Meyers. Murdoch and Dr. Ogden's relationship has yet to thaw but she seems to be coming around slowly. It all may be for naught as the detective has decided to make a social call on Mrs. Jones.
- Brackenreid is sure that Det. Murdoch can tell Dr. Ogden all about the automaton but to both his surprise and Julia's, Murdoch has a previous appointment. He leaves them to have dinner at Enid Jones' house.
- Enid hopes that Murdoch likes pot roast. He reveals that he does.
- William and Julia remain at odds about her having had an abortion.
- This episode takes place in Toronto 1896 – Victoria (Alexandrina Victoria 1819 - 1901) is Queen of the United Kingdom of Great Britain and Ireland, Defender of the Faith, and Empress of India.
- Prussic acid, also known as hydrocyanic acid or cyanide, is a rapidly acting, lethal toxin.
- Professor Ezra Delamore's research is into an application of the Babbage Difference Engine.
- The book Murdoch gets for Alwyn at the end, Steam Man of the Plains, was an actual novel printed in 1876 by Harold Cohen.
- The episode title is a possible allusion to Isaac Asimov's 1950 novel "I, Robot".
- This episode's opening murder is a possible allusion to the real life assassination in 1978 of Bulgarian dissident Gregori Markov, who was living in London, but the lethal pellet was full of ricin and was shot through an umbrella instead of a blind man's cane.
- Lori Spring was nominated for Gemini Awards' Best Writing in a Dramatic Series for this episode.
- Victoria Hall (Cobourg, Ontario) serves as the backdrop to the murder.
