“And,” the official went on, “our man says, further, that, as far as he knows, there is only one type of automatic pistol that fires a bullet as big as this one!”

“And that is?” asked the Chief.

“An improved pattern of the German Mauser pistol,” was the other’s startling reply.


The Chief tapped a cigarette meditatively on the back of his hand.

“Okewood,” he said, “you are the very model of discretion. I have put your reticence to a pretty severe test this morning, and you have stood it very well. But I can see that you are bristling with questions like a porcupine with quills. Zero hour has arrived. You may fire away!”

They were sitting in the smoking-room of the United Service Club. “The Senior,” as men call it, is the very parliament of Britain’s professional navy and army. Even in these days when war has flung wide the portals of the two services to all-comers, it retains a touch of rigidity. Famous generals and admirals look down from the lofty walls in silent testimony of wars that have been. Of the war that is, you will hear in every cluster of men round the little tables.

At luncheon the Chief had scrupulously avoided making, the slightest allusion to the thoughts with which Desmond’s mind was seething. Instead he had told, with the gusto of the born raconteur, a string of extremely droll yarns about “double crosses,” that is, obliging gentlemen who will spy for both sides simultaneously, he had come into contact with during his long and varied career. Desmond had played up to him and repressed the questions which kept rising to his lips. Hence the Chief’s unexpected tribute to him in the smoking room.

“Well,” said Desmond slowly, “there are one or two things I should like to know. What am I here for? Why did you have me followed last night? How did you know, before we ever went to Seven Kings, that Barney did not murder old Mackwayte? And lastly...”
