The question annoyed me, and I answered half in jest and half in earnest, “The day of the retreat we were really very little preoccupied by our own affairs, but I do believe, however, that an old agent and a woman did not succeed in getting behind our lines. I presume they remained in our house, where they used to stay before. But, Colonel, do you think the Germans will have permitted them to remain in our house? I do not think so. I am inclined to believe, however, that many of our peasant families which live isolated out in the country, have not been molested, and it would perhaps be better, if I should succeed in reaching the other side, to try to join one of these families. I know how deep is their affection for my father, and how greatly they love all that belongs to our family.” “Very well, think it over, and let me have an answer shortly. Meanwhile I want you to live here in the Intelligence Office, that you may become acquainted with the kind of information we receive concerning the doings on the other side. This will not prevent your flying, since I know that would displease you too much.” A broad smile passed over and illumined his soldierly face. “Here you will get a clearer notion of the possibilities of my project, and a better angle on the customs of the enemy in invaded territory. Therefore to-morrow you will be transferred to my department, without, however, binding yourself in any way to undertake the trip I have mentioned. I shall expect you to-morrow.” Our hands met in a firm, cordial clasp, and I left him. All night I could not sleep because of the thousands of plans I kept revolving in my mind. One plan suggested another, and then another, until there were heaps and heaps of them, confused, without beginning or end, just overlapping fragments of ideas. Towards dawn I slumbered a little, but I had to get up early to go to the office. On the fifteenth of January I became a part of that complicated organization which gathers and summarizes all the information the army has about the enemy. II
