"That is rather his affair, is it not?" she said drily.

"Precisely," her companion agreed. "Precisely! I should not, perhaps, have made the remark. Sickness, however, interests me very much. I have the misfortune not to be strong myself, and my own ailments occupy a good deal of my attention."

She looked at him curiously.

"You suffer from nerves, don't you?" she enquired.

"Hideously," he assented.

"And yet," she continued, still watching him in a puzzled fashion, "you made that extraordinary voyage through the air to catch this steamer. That doesn't seem to me to be at all the sort of thing a nervous person would do."

"It was for a bet," he explained confidentially. "The only occasion upon which I forget my nerves is when there is a bet to be lost or won. At the time," he went on, "my deportment was, I think, all that could have been desired. The sensations of which I was undoubtedly conscious I contrived to adequately conceal. The after-shock, however, has, I must admit, been considerable."

"Was it really so terribly important," she enquired, "that you should be in London next week?"

"The War Office made a special point of it," he assured her. "Got to join up, you know, directly I arrive."

"Do you think," she enquired after a brief pause, "that you will enjoy soldiering better than pseudo-diplomacy? I don't exactly know how to refer to your work. I only remember that when we were introduced I was told that you had something to do with the Secret Service."
