"Whatever Mr. Sage says we endorse," he replied gravely.
"Both of us?" she repeated.
"Both," said Malcolm Sage.
"I--I love him," she moaned; then after a pause she added: "It was to save the disgrace. He promised, he swore he would if I did it."
"Swore he would do what?" said Malcolm Sage.
"Marry me."
Malcolm Sage raised his eyes to Sir Lyster, who was standing implacable and merciless.
The girl"s head had fallen forward upon the table, and her shoulders were heaving convulsively.
Rising, Malcolm Sage walked across and placed his hand upon her arm.
"It will be better for everybody if you will try and control yourself," he said gently, "and above all tell us the truth."
As if surprised at the gentleness of his tone, she slowly raised her drawn face and looked at him in wonder.
"Now listen to me," continued Malcolm Sage, drawing up a chair and seating himself beside her, "and tell me if I am wrong. Whilst you were acting as Sir Lyster"s secretary you met Paul Cressit at the Admiralty, and you were attracted to him."
She nodded, with a quick indrawing of her breath.
"He made violent love to you and you succ.u.mbed. Later you took him into your confidence in regard to a certain matter and he promised to marry you. He put you off from time to time by various excuses.
You were almost distracted at the thought of the disgrace. He persuaded you to take a wax impression of Sir Lyster"s key, on the chance of it one day being useful."
Again she nodded, whilst the three men listened as if hypnotised.
"Finally he swore that he would marry you if you would steal this doc.u.ment, and he showed you a special license. Am I right?"
She nodded again, and then buried her head in her arms.
"I suppose," said Malcolm Sage quietly, "he did not happen to mention that he was already married?"
"Married!" She started up, her eyes blazing. "It isn"t true, oh! it isn"t true," she cried.
"I"m afraid it is," said Malcolm Sage, with feeling in his voice.
With a moan of despair her head fell forward upon the table, and hard dry sobs shook her frail body.
"Miss Blair," said Malcolm Sage presently, when she had somewhat regained her self-control, "my advice to you is to write out a full confession and bring it to me at my office to-morrow morning. It is your only chance: and now you must go to your room."
He rose, a.s.sisted her to her feet, and led her to the door, which he closed behind her.
"That I think concludes the enquiry," he said, as he walked over to the fireplace and, leaning against the mantelpiece, he began to fill his pipe. "Unless," he added, turning to Mr. Llewellyn John, "you would like to see Cressit."
The Prime Minister looked across at Sir Lyster and then at Lord Beamdale. Both shook their heads.
"What we should like, Sage," said Mr. Llewellyn John, "is a little information as to what has been happening."
With great deliberation Malcolm Sage proceeded to light his pipe.
When it was drawing to his entire satisfaction, he turned to Mr.
Llewellyn John and, with the suspicion of a fluttering at the corners of his mouth, remarked:
"I hope you have not been inconvenienced about the telephone."
"We could get no reply from the exchange," said Sir Lyster, "and the wire to the Admiralty is out of order."
"I had to disconnect you after I left this morning," said Malcolm Sage quietly. "My chauffeur swarmed up one of the standards.
Incidentally he wrecked an almost new pair of breeches."
"They"ll have to go in the Naval Estimates," cried Mr. Llewellyn John, who was feeling almost jovial now the tension of the past twenty-four hours had been removed.
"From the first," proceeded Malcolm Sage, "it was obvious that this theft was planned either at the Admiralty or at the War Office."
"That is absurd!" cried Sir Lyster with heat, whilst Lord Beamdale leaned forward, his usually apathetic expression of indifference giving place to one of keen interest.
"I accepted the a.s.surance that only three people in this house knew of the existence of the doc.u.ment," Malcolm Sage proceeded, as if there had been no interruption. "There was no object in any of those three persons stealing that to which they had ready access."
Lord Beamdale nodded his agreement with the reasoning.
"Therefore," continued Malcolm Sage, "the theft must have been planned by someone who knew about the doc.u.ment before it came here, and furthermore knew that it was to be here at a certain time. To confirm this hypothesis we have the remarkable circ.u.mstances that the blank paper subst.i.tuted for the original doc.u.ment was, in quality and the number of sheets, identical with that of the doc.u.ment itself."
"Good," e.j.a.c.u.l.a.t.ed Lord Beamdale, himself a keen mathematician.
Mr. Llewellyn John and Sir Lyster exchanged glances.
"It was almost, but not quite, obvious that the exchange had been effected by a woman."
"How obvious?" enquired Mr. Llewellyn John.
""Few women pa.s.s unperfumed to the grave,"" quoted Malcolm Sage. "I think it was Craddock who said that," he added, and Mr. Llewellyn John made a mental note of the phrase.
"The handle of the safe door was corrugated, and the lacquer had worn off, leaving it rough to the touch. When I kneeled down before the safe it was not to examine the metal work, but to see if the thief had left a scent."
"A scent?" repeated Sir Lyster.
"On the handle of the door there was a distinct trace of perfume, very slight, but I have a keen sense of smell, although a great smoker. On the doc.u.ment itself there was also evidence of a rather expensive perfume, not unlike that used by Miss Blair. Furthermore, it was bent in a rather peculiar manner, which might have resulted from its being carried in the belt of a woman"s frock. It might, of course, have been mere chance," he added; "but the envelope did not show a corresponding bend."
Again Lord Beamdale nodded appreciatively.
"Although several people have had an opportunity of taking a wax impression of the key, the most likely were Miss Blair and Walters-- that, however, was a side issue."
"How?" enquired Sir Lyster.
"Because primarily we were concerned with making the criminal himself or herself divulge the secret."
