"That is why I write this. My name is Humphreys. I was a sergeant in the 30th, and it was at Agra, when we were stationed there, that the change of infants took place. My wife went over to England. I took to drink and disgraced myself, and five years afterwards deserted. I stayed in England for some years and then enlisted again in the 5th Dragoon Guards, and being young-looking gave my age as eight years younger than I was. I now go by the name of Bowen, and am a sergeant and bear a good character in the regiment. The lad did not wish me to say anything about this, at any rate until the campaign was over; but as we shall be marching in a day or two, and it may be that I shall be killed, I write a letter to you and one to Captain Clinton, so that in case I am killed the truth may be known.
"I affirm most solemnly that the statement made by my wife was a lie. Whether she did intend to change the children or not is more than I can say. Sometimes she said she did, sometimes she said she didn't; but at any rate, she herself did not know which child was which, and did not discover the little mark on the shoulder until after the babies got mixed up. Over and over again I have seen her cry and wring her hands because she could not say which was which. She acknowledged that she meant to make money out of it, and lamented that she had lost her chance because she could never herself tell which was which. Of this I am ready to take my oath in any court of justice, and if she says she knows now, she is a liar. I have read this letter over to Troop-sergeant Matthews, and have in his presence sworn on a Bible to its truth. He will place his name by the side of mine as witness to that and to my signature. I remain, your obedient servant, John Humphreys, now known as John Bowen. The letter to your father is word for word the same as this. I have written it in duplicate in case you should be killed before I am."
"Well, that is plain enough," Easton said when Rupert had finished. "It is just what you said all along. The woman did not know which was her son, and you and Edgar stand in the same relation to Captain Clinton that you always did."
"Thank God for that!" Rupert said. "We want no change, and my father has said, talking it over with me again and again, he has two sons and loves us both equally, and it would be a deep grief to him now to know for certain that one of us is not his son. I will walk across to the hospital and ask how the sergeant is going on. I am strangely placed towards him now."
"It is a curious position," Easton said; "but in any case you do but stand towards him as a son would do towards a father who had given him up in infancy to be adopted by someone else."
Rupert did not reply, but, saying, "Wait here until I come back," walked over to the hospital lines. He returned in a few minutes.
"The doctor says he is sinking," he said gravely. "I shall go over there and remain until all is over."
"Will he be sensible at the last?" he asked the surgeon as he stood by the litter.
"Possibly," the surgeon said.
"I have a great interest in asking, doctor; I am most anxious to have a few words with him if possible before he dies."
