- [Opel is showing Cradock the gold bars in his bank vault]
- Det. Chief Supt. Cradock: You also refine gold?
- Opel: Oh yes, we are licensed refiners - like the Rand Refinery at Germiston or your Johnson Matthey in London. We make all sizes of bars. Like chocolate, it makes a nice present.
- Det. Chief Supt. Cradock: Yes I'm sure it does.
- Opel: What a pity you Britishers are not allowed to have gold.
- Det. Chief Supt. Cradock: [flippantly] Not unless we steal it.
