'It is life and death,' he said solemnly. 'I can put it no higher and no lower. Once we know what is the menace we can meet it. As long as we are in the dark it works unchecked and we may be too late. The war must be won or lost in Europe. Yes; but if the East blazes up, our effort will be distracted from Europe and the great _coup may fail. The stakes are no less than victory and defeat, Hannay.'
I got out of my chair and walked to the window. It was a difficult moment in my life. I was happy in my soldiering; above all, happy in the company of my brother officers. I was asked to go off into the enemy's lands on a quest for which I believed I was manifestly unfitted - a business of lonely days and nights, of nerve-racking strain, of deadly peril shrouding me like a garment. Looking out on the bleak weather I shivered. It was too grim a business, too inhuman for flesh and blood. But Sir Walter had called it a matter of life and death, and I had told him that I was out to serve my country. He could not give me orders, but was I not under orders -higher orders than my Brigadier's? I thought myself incompetent, but cleverer men than me thought me competent, or at least competent enough for a sporting chance. I knew in my soul that if I declined I should never be quite at peace in the world again. And yet Sir Walter had called the scheme madness, and said that he himself would never have accepted.
How does one make a great decision? I swear that when I turned round to speak I meant to refuse. But my answer was Yes, and Ihad crossed the Rubicon. My voice sounded cracked and far away.
Sir Walter shook hands with me and his eyes blinked a little.
'I may be sending you to your death, Hannay - Good God, what a damned task-mistress duty is! - If so, I shall be haunted with regrets, but you will never repent. Have no fear of that. You have chosen the roughest road, but it goes straight to the hill-tops.'
He handed me the half-sheet of note-paper. On it were written three words - '_Kasredin', '_cancer', and '_v. _I.'
'That is the only clue we possess,' he said. 'I cannot construe it, but I can tell you the story. We have had our agents working in Persia and Mesopotamia for years - mostly young officers of the Indian Army. They carry their lives in their hands, and now and then one disappears, and the sewers of Baghdad might tell a tale.
But they find out many things, and they count the game worth the candle. They have told us of the star rising in the West, but they could give us no details. All but one - the best of them. He had been working between Mosul and the Persian frontier as a muleteer, and had been south into the Bakhtiari hills. He found out something, but his enemies knew that he knew and he was pursued.
Three months ago, just before Kut, he staggered into Delamain's camp with ten bullet holes in him and a knife slash on his forehead.
He mumbled his name, but beyond that and the fact that there was a Something coming from the West he told them nothing. He died in ten minutes. They found this paper on him, and since he cried out the word "Kasredin" in his last moments, it must have had something to do with his quest. It is for you to find out if it has any meaning.'
I folded it up and placed it in my pocket-book.
'What a great fellow! What was his name?' I asked.
Sir Walter did not answer at once. He was looking out of the window. 'His name,' he said at last, 'was Harry Bullivant. He was my son. God rest his brave soul!'
