“Wonder if they’ll let us?” said Simon, doubtfully. “I haven’t seen anything about it in the booklets that they issue.”

“That we must find out, but, in any case, they will not prevent me taking a ticket through to Vladivostok, and as all the trains stop at Sverdlovsk, I can drop off there. I think I should tell you, my friend, that it is not my intention that you should accompany me on this journey.”

“Oh! Why?” Simon’s eyes flickered towards his friend.

“There are a variety of reasons,” said De Richleau, quietly. “You are, I think, very happily engaged here, in Moscow — it would be a pity to curtail your visit. It was by your quick wit that we discovered Jack Straw, which, in turn, supplied us with the reason for Rex’s visit to Russia. It is you, again, who have discovered his whereabouts — whereas, so far, I have done nothing. It is my turn now. When I step off the train at Sverdlovsk, I shall, I think, be outside the law; it would be a great comfort to me to have you here in Moscow, safe and free, and able, if I do not return in a short time, to stir up the Embassies on my behalf. It would be sheer foolishness for both of us to run our heads into the noose.”

“Um — I agree,” said Simon quickly, “very silly. It’s a good thing that you know the people at the Embassies too — you’ll have much more pull than I should. Obviously, you stay here, and I go to Tobolsk!”

“But, my friend — do not be foolish!” De Richleau frowned.

“I’m not.” Simon gave his jerky little laugh. “Now I’ll tell you. I didn’t get that information about Rex for nothing. Valeria Petrovna got it from Leshkin, but he made her promise that I should be out of Moscow by tonight, so that settled it!”

“Indeed!” said the Duke, with surprise. “But, even so, I fear it does not solve our problem. How will you manage in Tobolsk? You can speak no Russian!”

“Um!” Simon was a little dashed. “That’s a bit awkward!”

“We will both go,” said the Duke, with decision, “and I will confess that I shall be more glad to have you with me.”
