'Monsieur, you mistake my title. Although my uncle is a marquis, I am but Lady Alicia.'

'Your pardon, my lady. For the moment I was back in that scintillating Court which surrounded Louis le Grand.'

'How flatteringly you introduce yourself, monsieur. In the gallery upstairs there is a painting of the Marquise de Bellairs, and when I show it to your tomorrow, you will then understand how charmingly you have pleased a vain woman by your reference to that beautiful lady. But I must not talk in this frivolous strain, monsieur. There is serious business to be considered, and I assure you I looked forward to your coming, monsieur, with the eagerness of Sister Anne in the tower of Bluebeard.'

I fear my expression as I bowed to her must have betrayed my gratification at hearing these words, so confidentially uttered by lips so sweet, while the glance of her lovely eyes was even more eloquent than her words. Instantly I felt ashamed of my chaffering over terms with her uncle; instantly I forgot my resolution to depart on the morrow; instantly I resolved to be of what assistance I could to this dainty lady. Alas! the heart of Valmont is today as unprotected against the artillery of inspiring eyes as ever it was in his extreme youth.

'This house,' she continued vivaciously, 'has been practically in a state of siege for two months. I could take none of my usual walks in the gardens, on the lawns, or through the park, without some clumsy policeman in uniform crashing his way through the bushes, or some detective in plain clothes accosting me and questioning me under the pretence that he was a stranger who had lost his way. The lack of all subtlety in our police is something deplorable. I am sure the real criminal might have passed through their hands a dozen times unmolested, while our poor innocent servants, and the strangers within our gates, were made to feel that the stern eye of the law was upon them night and day.'

The face of the young lady was an entrancing picture of animated indignation as she gave utterance to this truism which her countrymen are so slow to appreciate. I experienced a glow of satisfaction.

'Yes,' she went on, 'they sent down from London an army of stupid men, who have kept our household in a state of abject terror for eight long weeks, and where are the emeralds?'

As she suddenly asked this question, in the most Parisian of accents, with a little outward spreading of the hand, a flash of the eye, and a toss of the head, the united effect was something indescribable through the limitations of the language I am compelled to use.

'Well, monsieur, your arrival has put to flight this tiresome brigade, if, indeed, the word flight is not too airy a term to use towards a company so elephantine, and I assure you a sigh of relief has gone up from the whole household with the exception of my uncle. I said to him at dinner tonight: "If Monsieur Valmont had been induced to take an interest in the case at first, the jewels would have been in my possession long before tonight."'

'Ah, my lady,' I protested, 'I fear you overrate my poor ability. It is quite true that if I had been called in on the night of the robbery, my chances of success would have been infinitely greater than they are now.'
