“Remember? I guess I do. I had a hand in that; gave orders to a squad of the Marines to get him; one of them had some dope on him. Well, I’m glad to meet you, young man. But how about that shoulder? Get over it and come back to us?” “Oh, he’s the right stuff, you may bet that!” put in the surgeon, searching for the list. “I believe you, Major, and that’s what we want. Spin that full yarn about the spy to me, will you, Richards?” Don looked a little sheepish; he did not much like to talk about himself, but Major Little said: “Colonel Walton is in part command of one branch of the enemy Intelligence Division here.” And Don related fully his part in the spy affair, beginning even with the capture of the spy’s confederates back in the States and the important part also that Clement Stapley had performed. The colonel listened with much interest; then turned and spoke to the major: “Doctor, you have about as many men as you really need now for drivers, haven’t you?” “Yes, but we can always make room for another expert at it.” “Or you can let one go if he can be of more use elsewhere. We must have more men who are keen on spy work and this lad is a go-getter in that particular. Will you turn him over to me? You wouldn’t mind becoming a liaison officer; would you, Richards; also a messenger at times; that is, to all appearances? Your work will really be that of army detective, to operate in some little measure with the military police at times, when necessary, but to gain intelligence of what the enemy may be trying to do within our lines in seeking information. In short, to stop him from getting information. Agreed?” “Anything,” Don replied, “to help lick the Huns! “You have an automatic and ammunition? Good! Clothes and shoes O.K.? Fine! Continue to wear your Red Cross arm band. Now then, report first to headquarters of the First Army Corps and then to Captain Lowden, with the Twenty-eighth Division in the field. We have some information from him. By the time you can get there the advance will be under way and you’ll probably catch up with the boys somewhere west of the Aire River; their orders, I believe, are to attack in the Argonne sector. You will find an ambulance or a lorry going up; the pass I shall give you will take you anywhere. You are starting out without any definite information now, but such may come to you from time to time. Now then, I’ll swear you and you can get on the job at once. Your rank will be a sergeant of infantry; the pay----” “I don’t care what the pay is, Colonel. It’s the duty I’m after,” Don said.
