“Go to the ‘Intourist’ and arrange for a stay of perhaps a fortnight in Moscow; let them obtain your passport visa in the ordinary way — that will take some little time. Book by the direct route to Moscow, via Berlin and Warsaw — you will cross the frontier at Negoreloye; I will meet you in Moscow after making my inquiries in Helsingfors, and combing the Consulates in Leningrad for any information which they may have.”

Simon nodded his bird-like head. “What about the Embassies here. I suppose you’ve done what you can?”

“Yes, but quite uselessly. The American Embassy had already been questioned by Washington on behalf of Channock Van Ryn, but they could add nothing to Moscow’s report that ‘Rex left on December 11th for an unknown destination’.”

“How about mun?”

“Who?” asked the Duke, vaguely.

“Money — I mean,” Simon corrected with a grin.

“I would suggest a good supply; at one time visitors to the Soviet were forced to deposit all foreign money at the frontier; they were given Soviet roubles in exchange, and any surplus of these which they had left over they could exchange once more into their own currency when they left the country; but that is so no longer. It is permissible to carry any currency into Russia, only the amount must be declared, in order that no question can be raised as to taking it out again.”

“Won’t they be suspicious if I — er — bring in more than I should need in the ordinary way?”

“Yes, perhaps. Therefore it would be best if you declare only one third of what you bring; conceal the rest about you — in your boots or the lining of your waistcoat. I am sending a reserve for myself by way of that excellent Embassy bag. It is quite possible that we may need a considerable sum for bribes, and, if we can find Rex, for arranging a method by which he can be smuggled out of the country. If we declare all that we have when we go in — it might be difficult to explain upon what it has been expended, when we go out. You must remember that all travels, hotels, food — practically everything is supposed to be paid for before we start.”

“Jack Straw?” queried Simon, suddenly “I can’t help wondering what he meant by that. Do you think there’s anything to be done there?”
