chunk: Von Bruning invites them to Dollmann's villa for a dinner, where he attempts to subtly cross-examine them to find out if they are British spies. Carruthers plays a dangerous game, admitting they are curious. But he convinces Von Bruning that he believes the cover story about treasure and merely wants to see the imaginary "wreck". Carruthers announces that the Foreign Office has recalled him to England. He heads off, then doubles back to follow Von Bruning and his men. He trails them to a port where they board a tugboat towing a barge. Carruthers sneaks aboard and hides, and the convoy heads to sea.
