"This sheet," explained Irene, "is, in fact, but a part of a letter. The first sheets are missing, so we don't know who it was addressed to; but it is signed, at the end, by the initials 'E. de V.'"
 
"The ambassador!" cried Hathaway, caught off his guard by surprise.
 
"The same," said O'Gorman triumphantly; "and it is all in his well-known handwriting. Read the letter, my girl."
 
"The first sentence," said Irene, "is a continuation of something on a previous page, but I will read it just as it appears here."
 
And then, in a clear, distinct voice that was audible to all present, she read as follows:
 
"which forces me to abandon at once my post and your delightful country in order to avoid further complications. My greatest regret is in leaving Mrs. Burrows in so unfortunate a predicament. The lady was absolutely loyal to us and the calamity that has overtaken her is through no fault of her own.
 
"That you may understand this thoroughly I will remind you that John Burrows was in our employ. It was through our secret influence that he obtained his first government position, where he inspired confidence and became trusted implicitly. He did not acquire full control, however, until five years later, and during that time he met and married Beatrice Hathaway, the charming daughter of James J. Hathaway, a wealthy broker. That gave Burrows added importance and he was promoted to the high government position he occupied at the time of his death.
 
"Burrows made for us secret copies of the fortifications on both the east and west coasts, including the number and caliber of guns, amounts of munitions stored and other details. Also he obtained copies of the secret telegraph and naval codes and the complete armaments of all war vessels, both in service and in process of construction. A part of this information and some of the plans he delivered to me before he died, as you know, and he had the balance practically ready for delivery when he was taken with pneumonia and unfortunately expired very suddenly.
 
"It was characteristic of the man's faithfulness that on his death bed he made his wife promise to deliver the balance of the plans and an important book of codes to us as early as she could find an opportunity to do so. Mrs. Burrows had previously been in her husband's confidence and knew he was employed by us while holding his position with the government, so she readily promised to carry out his wishes, perhaps never dreaming of the difficulties that would confront her or the personal danger she assumed. But she was faithful to her promise and afterward tried to fulfill it.
 
"Her father, the James J. Hathaway above mentioned, in whose mansion Mrs. Burrows lived with her only child, is a staunch patriot. Had he known of our plot he would have promptly denounced it, even sacrificing his son-in-law. I have no quarrel with him for that, you may well believe, as I value patriotism above all other personal qualities. But after the death of John Burrows it became very difficult for his wife to find a way to deliver to me the packet of plans without being detected. Through some oversight at the government office, which aroused suspicion immediately after his death, Burrows was discovered to have made duplicates of many documents intrusted to him and with a suspicion of the truth government agents were sent to interview Mrs. Burrows and find out if the duplicates were still among her husband's papers. Being a clever woman, she succeeded in secreting the precious package and so foiled the detectives. Even her own father, who was very indignant that a member of his household should be accused of treason, had no suspicion that his daughter was in any way involved. But the house was watched, after that, and Mrs. Burrows was constantly under surveillance—a fact of which she was fully aware. I also became aware of the difficulties that surrounded her and although impatient to receive the package I dared not press its delivery. Fortunately no suspicion attached to me and a year or so after her husband's death I met Mrs. Burrows at the house of a mutual friend, on the occasion of a crowded reception, and secured an interview with her where we could not be overheard. We both believed that by this time the police espionage had been greatly relaxed so I suggested that she boldly send the parcel to me, under an assumed name, at Carver's Drug Store, where I had a confederate. An ordinary messenger would not do for this errand, but Mr. Hathaway drove past the drug store every morning on his way to his office, and Mrs. Burrows thought it would be quite safe to send the parcel by his hand, the man being wholly above suspicion.
 
"On the morning we had agreed upon for the attempt, the woman brought the innocent looking package to her father, as he was leaving the house, and asked him to deliver it at the drug store on his way down. Thinking it was returned goods he consented, but at the moment he delivered the parcel a couple of detectives appeared and arrested him, open............
