- Let's race back and give Ms. Starr a warning.

- Nuisance. She's smitten with him. She'd scoff at us.

- So what do we do?

- We can't protect her, but we can save her jewels and at the same time set a trap.

- Great. How?

- We substitute fake jewels with the real ones. Treat it in a reactor to leave radioactive traces of the thief.

- Terrific!

- There's just one problem.
