- Detective William Murdoch: Would a guilty person be so guileless?
- Inspector Thomas Brackenreid: Only if his guilessness was an act.
- Inspector Thomas Brackenreid: [with some annoyance] You've got guts, Crabtree... not much in the way of brains... but guts.
- Detective William Murdoch: [looking at the body that has fallen for apparently no reason] Seal all exits, George. This man's been murdered!
- Detective William Murdoch: [running into the room excitedly] George, I've cracked the code!. Arrest them ! Arrest them all!
