"Harry," he said, "the war has hit us already. I'm called home by cable, and at the same time there is word that your Aunt Mary is seriously ill. Your mother wants to be with her. I find that, by a stroke of luck, I can get quarters for your mother and myself on to-morrow's steamer. But there's no room for you. Do you think you could get along all right if you were left here? I'll arrange for supplies for the house; Mrs. Grimshaw can keep house. And you will have what money you need."

"Of course I can get along!" said Harry, stoutly. "I suppose the steamers are fearfully crowded?"

"Only about half of them are now in service," said Mr. Fleming. "And the rush of Americans who have been travelling abroad is simply tremendous. Well, if you can manage, it will relieve us greatly. I think we'll be back in less than a month. Keep out of mischief. And write to us as often as you can hear of a steamer that is sailing. If anything happens to you, cable. I'll arrange with Mr. Bruce, at the Embassy, to help you if you need him, but that ought not to be necessary."

Harry was genuinely sorry for his mother's distress at leaving him, but he was also relieved, in a way. He felt now he would not be forbidden to do his part with the scouts. He would be able to undertake what promised to be the greatest adventure that had ever come his way. He had no fear of being left alone for his training as a Boy Scout had made him too self reliant for that.

Mr. and Mrs. Fleming started for Liverpool that night. Train service throughout the country was so disorganized by the military use of the railways that journeys that in normal, peaceful times required only two or three hours were likely to consume a full day. So he went into the city of London with them and saw them off at Euston, which was full of distressed American refugees.

The Flemings found many friends there, of whose very presence in London they were ignorant, and Mr. Fleming, who, thanks to his business connections in London, was plentifully supplied with cash, was able to relieve the distress of some of them.

Many had escaped from France, Germany and Austria with only the clothes they wore, having lost all their luggage. Many more, though possessed of letters of credit or travellers' checks for considerable sums, didn't have enough money to buy a sandwich, since the banks were all closed and no one would cash their checks.

So Harry had another glimpse of the effects of war, seeing how it affected a great many people who not only had nothing to do with the fighting, but were citizens of a neutral nation. He was beginning to understand very thoroughly by this time that war was not what he had always dreamed. It meant more than fighting, more than glory.

But, after all, now that war had come, it was no time to think of such things. He had undertaken, if he could get permission, to do a certain very important piece of work. And now, by a happy accident, as he regarded it, it wasn't necessary for him to ask that permission. He was not forbidden to do any particular thing; his father had simply warned him to be careful.

So when he went home, he whistled outside of Dick Mercer's window, woke him up, and, when Dick came down into the garden, explained to him what Colonel Throckmorton wanted them to do.
