Captain Young tells the royal family that the police will control the cards, and if they wanted the cards from the Klondikes back, they must tell all the secrets about the cards.
It's absolutely pointless 
for the police to plot anything.
Es bringt der Polizei überhaupt nichts,
irgendwelche Pläne zu schmieden.
Todo lo que trame
la policía será en vano.
La polizia non può tramare nulla
contro di noi, è inutile.
É totalmente inútil a polícia
tramar qualquer coisa.
Что бы полиция ни задумала,
ничего не выйдет.
