- Constable George Crabtree: [Looking at the recently unearthed mummified bodies] Cyanide is often used in suicides. Perhaps they killed themselves.
- Detective William Murdoch: How did they then bury themselves, George?
- Constable George Crabtree: [Sheepishly] Point taken, sir.
- Inspector Thomas Brackenreid: So, whoever built this shed did it to conceal the bodies.
- Detective William Murdoch: That would be the owner of the factory - a James Kirkham. I've asked George to find him and determine the nature of his business. I did ask him to be quick about it.
- Inspector Thomas Brackenreid: [Sarcastically] Oh, good, because with a five year-old case, we wouldn't want the trail to go cold, would we?
