“ ‘For two years we have carried on this work unharmed, but I suppose it cannot go on forever. Some day my disguise will be penetrated, and all will be over with me. Some day Father will meet with some violent end when he is alone and unprotected, and no one will be found to answer for the deed. But it will all be for the glory of the Union we delight to serve. Now do you understand the situation?
“ ‘I do not get home here often, and never except for the purpose of conveying some message that will best be sent to headquarters through this channel. My field of service is with the armies south of the Potomac. But while I am here now, Father and I have consulted as to the best way of communicating this news to you and have decided on this means. We cannot tell how soon our end may come. Father tells me there are rumors about here that we are serving the Confederate side. Should you return unexpectedly and find us gone, and perhaps hear those rumors, you would certainly be justified in putting the worst construction on our actions.
“ ‘So we have decided to write and leave you this message. It will be left carelessly among Father’s papers, and without the cipher will, of course, be unreadable by any one. But we have not yet decided in what place to conceal the cipher where there is no danger of its being discovered. That is a military secret and, if it were disclosed, would be fatal and far-reaching in its consequences.’ ”
Miss Camilla stopped there, and her spellbound listeners drew a long breath.
“Isn’t it wonderful!” breathed Doris. “And they were loyal and devoted to the Union all the time. How happy you must be, Miss Camilla.”
“I am happy,—beyond words!” she replied. “But that is not quite all of it. So far, it was evidently written at one sitting, calmly and coherently. There is a little more, but it is hasty and confused, and somewhat puzzling. It must have been added at another time, and I suspect now, probably just at the time of my return. There is a blank half-page, and then it goes on:
“ ‘In a great hurry. Most vital and urgent business has brought me back to see Father. Just learned you were here. There is grave, terrible danger. The rebels are invading. I am with them, of course. Not far away. Must return tonight, at once, to lines, if I ever get there alive. Have a task before me that will undoubtedly see the end of me. In this rig and in this place am open to danger from friend and foe alike. But there is no time to change. Hope for best. Forgive haste but there is not a moment to lose. Father seems ill and unlike himself. He saw two or three Confederate spies at the house today. Always suspect something is wrong after such a meeting. Don’t be surprised at state of the house. Unavoidable but all right. Father will explain where I have hidden this cipher code. Always your loving brother,
“ ‘Roland.’
“And there is one more strange line,” ended Miss Camilla. “It is this:
“ ‘In case you should forget, or Father doesn’t tell you, right hand side from house, behind 27.’ ”
