'Certainly, my lady.'
'Very well, Monsieur Valmont, I shall supply any deficiencies that occur in my uncle's conversation with you. There is one point on which I should like to warn you. Both my uncle and the police have made up their minds that a certain young man is the culprit. The police found several clues which apparently led in his direction, but they were unable to find enough to justify his arrest. At first I could have sworn he had nothing whatever to do with the matter, but lately I am not so sure. All I ask of you until we secure another opportunity of consulting together is to preserve an open mind. Please do not allow my uncle to prejudice you against him.'
'What is the name of this young man?'
'He is the Honourable John Haddon.'
'The Honourable! Is he a person who could do so dishonourable an action?'
The young lady shook her head.
'I am almost sure he would not, and yet one never can tell. I think at the present moment there are one or two noble lords in prison, but their crimes have not been mere vulgar housebreaking.'
'Am I to infer, Lady Alicia, that you are in possession of certain facts unknown either to your uncle or the police?'
'Yes.'
'Pardon me, but do these facts tend to incriminate the young man?' Again the young lady leaned back in her chair, and gazed past me, a wrinkle of perplexity on her fair brow. Then she said very slowly:—
'You will understand, Monsieur Valmont, how loath I am to speak against one who was formerly a friend. If he had been content to remain a friend, I am sure this incident, which has caused us all such worry and trouble, would never have happened. I do not wish to dwell on what my uncle will tell you was a very unpleasant episode, but the Honourable John Haddon is a poor man, and it is quite out of the question for one brought up as I have been to marry into poverty. He was very headstrong and reckless about the matter, and involved my uncle in a bitter quarrel while discussing it, much to my chagrin and disappointment. It is as necessary for him to marry wealth as it is for me to make a good match, but he could not be brought to see that. Oh, he is not at all a sensible young man, and my former friendship for him has ceased. Yet I should dislike very much to take any action that might harm him, therefore I have spoken to no one but you about the evidence that is in my hands, and this you must treat as entirely confidential, giving no hint to my uncle, who is already bitter enough against Mr. Haddon.'
'Does this evidence convince you that he stole the necklace?'
'No; I do not believe that he actually stole it, but I am persuaded he was an accessory after the fact—is that the legal term? Now, Monsieur Valmont, we will say no more tonight. If I talk any longer about this crisis, I shall not sleep, and I wish, assured of your help, to attack the situation with a very clear mind tomorrow.'
When I retired to my room, I found that I, too, could not sleep, although I needed a clear mind to face the problem of tomorrow. It is difficult for me to describe accurately the effect this interview had upon my mind, but to use a bodily simile, I may say that it seemed as if I had indulged too freely in a subtle champagne which appeared exceedingly excellent at first, but from which the exhilaration had now departed. No man could have been more completely under a spell than I was when Lady Alicia's eyes first told me more than her lips revealed; but although I had challenged her right to the title 'mercenary' when she applied it to herself, I could not but confess that her nonchalant recital regarding the friend who desired to be a lover jarred upon me. I found my sympathy extending itself to that unknown young man, on whom it appeared the shadow of suspicion already rested. I was confident that if he had actually taken the emeralds it was not at all from motives of cupidity. Indeed that was practically shown by the fact that Scotland Yard found itself unable to trace the jewels, which at least they might have done if the necklace had been sold either as a whole or dismembered. Of course, an emerald weighing an ounce is by no means unusual. The Hope emerald, for example, weighs six ounces, and the gem owned by the Duke of Devonshire measures two and a quarter inches through its greatest diameter. Nevertheless, such a constellation as the Blair emeralds was not to be disposed of very easily, and I surmised no attempt had been made either to sell them or to raise money upon them. Now that I had removed myself from the glamour of her presence, I began to suspect that the young lady, after all, although undoubtedly possessing the brilliancy of her jewels, retained also something of their hardness. There had been no expression of sympathy for the discarded friend; it was too evident, recalling what had latterly passed between us, that the young woman's sole desire, and a perfectly natural desire, was to recover her missing treasure. There was something behind all this which I could not comprehend, and I resolved in the morning to question the Marquis of Blair as shrewdly as he cared to allow. Failing him, I should cross-question the niece in a somewhat dryer light than that which had enshrouded me during this interesting evening. I care not who knows it, but I have been befooled more than once by a woman, but I determined that in clear daylight I should resist the hypnotising influence of those glorious eyes. Mon Dieu! Mon Dieu! how easy it is for me to make good resolutions when I am far from temptation!
It was ten o'clock next morning when I was admitted to the study of the aged bachelor Marquis of Blair. His keen eyes looked through and through me as I seated myself before him.
'Well!' he said shortly.
'My lord,' I began deliberately, 'I know nothing more of the case than was furnished by the accounts I have read in the newspapers. Two months have elapsed since the robbery. Every day that passed made the detection of the criminal more difficult. I do not wish to waste either my time or your money on a forlorn hope. If, therefore, you will be good enough to place me in possession of all the facts known to you, I shall tell you at once whether or not I can take up the case.'
'Do you wish me to give you the name of the criminal?' asked his lordship.
'Is his name known to you?' I asked in return.
'Yes. John Haddon stole the necklace.'
'Did you give that name to the police?'
'Yes.'
'Why didn't they arrest him?'
'Because the evidence against him is so small, and the improbability of his having committed the crime is so great.'
'What is the evidence against him?'
His lordship spoke with the dry deliberation of an aged solicitor.
'The robbery was committed on the night of October the fifth. All day there had been a heavy rain, and the grounds were wet. For reasons into which I do not care to enter, John Haddon was familiar with this house, and with our grounds. He was well known to my servants, and, unfortunately, popular with them, for he is an openhanded spendthrift. The estate of his elder brother, Lord Steffenham, adjoins my own to the west, and Lord Steffenham's house is three miles from where we sit. On the night of the fifth a ball was given in the mansion of Lord Steffenham, to which, of course, my niece and myself were invited, and which invitation we accepted. I had no quarrel with the elder brother. It was known to John Haddon that my niece intended to wear her necklace of emeralds. The robbery occurred at a time when most crimes of that nature are committed in country houses, namely, while we were at dinner, an hour during which the servants are almost invariably in the lower part of the house. In October the days are getting short. The night was exceptionally dark, for, although the rain had ceased, not a star was visible. The thief placed a ladder against the sill of one of the upper windows, opened it, and came in. He must have been perfectly familiar with the house, for there are evidences that he went direct to the boudoir where the jewel case had been carelessly left on my niece's dressing table when she came down to dinner. It had been taken from the strong room about an hour before. The box was locked, but, of course, that made no difference. The thief wrenched the lid off, breaking the lock, stole the necklace, and escaped by the way he came.'
'Did he leave the window open, and the ladder in place?'
'Yes.'
'Doesn't
