The officer nodded. “Who is Miss Marshall, if I am permitted to ask? I know it seems an impertinence on my part to question an officer, but I want to know,” declared the Overton girl laughing. “I believe that is quite a common excuse with women for asking questions, but it is comprehensive.” The captain glanced about them and invited Grace to sit down with him on a bench. The air was quite chill, but the view up and down the river was an attractive one. “What I am about to say is strictly confidential. I am giving it to you for your own guidance, now that you belong to our Intelligence Department.” “Strange, sir, that I have not heard of that.” “Yes, you are a member. To return to the subject, Molly Marshall is one of the cleverest operators in the Secret Service.” “A spy?” The captain shrugged his shoulders. “I never liked the word when applied to our own. She is an investigator and a brilliant operator. I shall be glad to have you know her, and assure you that you may trust her fully.” “Thank you, but I do not believe I should care to trust any one in these confidential matters, unless I knew her pretty well. I should like to meet her, just the same, but she is not to know that I am doing anything in the investigating line, if you will be so good as to keep that fact confidential.” The captain promised, saying it was not generally customary for Secret Service operators with the army to know each other, as such an acquaintance opened the way for many errors of judgment. “You are perfectly right in the position you take,” he added. “You possess all the makings of a brilliant operator yourself.” Grace thanked him. “As I have said before, I have no aspirations in that direction, at least not beyond the point that I can serve my country. Perhaps my woman’s curiosity in combination with my woman’s intuition is responsible for my being in it to the extent that I am. You will observe that I am not backward about paying my sex compliments. However, it will soon be ended and then we shall all return to our previous lives--if we can. How about you, sir, shall you continue in the Service?” “I think not.” Grace rose and, thanking the captain, said she must be on her way to the canteen at Number Two. On her way she encountered a Chinaman and told him if he should see Won Lue to send him to the canteen. Rather to her amazement Won was waiting for her when she arrived there. Won shook hands with himself and smiled broadly. “You may be able to help us here to-day, Won. Are you working?” The Chinaman shook his head negatively. “You savvy plidgin?” he asked. “No.” “Me savvy plenty plidgin, a-la. Plidgin all fly away. No more plidgin.” Grace understood his meaning. The pigeon-flying came to an end when the army reached the Rhine, for there the enemy agents could work more directly and without much danger of being caught. That was what they were doing at that very moment.
