- DI Lewis: [to Stella Drew] I'm sorry. We're police officers. Decisions about the future of mankind don't really feature in our job description.
- Dr. Yardley: Hundreds of students pass through this college every year. I can't be expected to remember them all.
- DI Lewis: Not even the ones who mysteriously vanish? There can't be too many of those surely.
- Stella Drew: [Referring to missing student Soo] She worked for a few of us in the group, vaguely competently as I remember.
- DI Lewis: [Sarcastically] That good?
- Stella Drew: Well, she wasn't exceptional.
- DI Lewis: But according to the missing person's report she seems to have been extremely clever.
- Stella Drew: Well, it's Oxford, Inspector. Everyone's extremely clever.
- DI Lewis: [Referring to the desiccated body discovered in the attic] Any idea how long she's been up here?
- Dr. Laura Hobson: A decade or more. Really not my area, I'm afraid.
