“If,” continued the Colonel, “the air line services had not been suspended we could send you by aeroplane to Brindisi. But they are suspended-the earthquake, you understand. Everything is disorganized. The planes are being used for relief work. But we can do without them. It will be best if you go by sea.”

“But surely …”

“There is an Italian shipping line which runs a weekly service of small cargo boats between here and Genoa. Sometimes, when there is a cargo, they go up as far as Constanza, but usually they run only as far as here, calling at the Piræus on the way. They carry a few passengers, fifteen at the most, and we can make sure that every one of them is harmless before the boat is given its clearance papers. When you get to Genoa, you will have only the short train journey between Genoa and the French frontier to put you out of reach of German agents.”

“But as you yourself pointed out, time is an important factor. To-day is the second. I am due back on the eighth. If I have to wait for boats I shall be days late. Besides, the journey itself will take at least a week.”

“There will be no delay, Mr. Graham,” sighed the Colonel. “I am not stupid. I telephoned the port police before you arrived. There is a boat leaving in two days’ time for Marseilles. It would have been better if you could have travelled on that even though it does not ordinarily take passengers. But the Italian boat leaves to-day at four-thirty in the afternoon. You will be able to stretch your legs in Athens to-morrow afternoon. You will dock in Genoa early Saturday morning. You can, if you wish and if your visas are in order, be in London by Monday morning. As I have told you, a marked man has advantages over his enemies: he can run away-disappear. In the middle of the Mediterranean, you will be as safe as you are in this office.”

Graham hesitated. He glanced at Kopeikin; but the Russian was staring at his finger nails.

“Well, I don’t know, Colonel. This is all very good of you, but I can’t help thinking that, in view of the circumstances which you have explained to me, I ought to get in touch with the British Consul here, or with the British Embassy, before deciding anything.”

Colonel Haki lit a cigarette. “And what do you expect the Consul or the Ambassador to do? Send you home in a cruiser?” He laughed unpleasantly. “My dear Mr. Graham, I am not asking you to decide anything. I am telling you what you must do. You are, I must again remind you, of great value to my country in your present state of health. You must allow me to protect my country’s interests in my own way. I think that you are probably tired now and a little upset. I do not wish to harass you, but I must explain that, if you do not agree to follow my instructions, I shall have no alternative but to arrest you, have an order issued for your deportation and put you on board the Sestri Levante under guard. I hope that I make myself clear.”

Graham felt himself reddening. “Quite clear. Would you like to handcuff me now? It will save a lot of trouble. You need …”

“I think,” put in Kopeikin hastily, “that I should do as the Colonel suggests, my dear fellow. It is the best thing.”
