His words astonished me. Was I on the verge of hearing a confession? It almost amounted to that already.

'Mr. Dacre,' I said, 'I cannot enter into the subtleties you pursue. My duty is to find the criminal.'

'Again I say you are in the right, Monsieur Valmont, and I am enchanted to find so sensible a head on French shoulders. Although you are a more recent arrival, if I may say so, than myself, you nevertheless already give utterance to sentiments which do honour to England. It is your duty to hunt down the criminal. Very well. In that I think I can aid you, and thus have taken the liberty of requesting your attendance here this morning. Let me fill your glass again, Monsieur Valmont.'

'No more, I beg of you, Mr. Dacre.'

'What, do you think the receiver is as bad as the thief?'

I was so taken aback by this remark that I suppose my face showed the amazement within me. But the young man merely laughed with apparently free-hearted enjoyment, poured some wine into his own glass, and tossed it off. Not knowing what to say, I changed the current of conversation.

'Mr. Gibbes said you had been kind enough to recommend me to his attention. May I ask how you came to hear of me?'

'Ah! who has not heard of the renowned Monsieur Valmont,' and as he said this, for the first time, there began to grow a suspicion in my mind that he was chaffing me, as it is called in England—a procedure which I cannot endure. Indeed, if this gentleman practised such a barbarism in my own country he would find himself with a duel on his hands before he had gone far. However, the next instant his voice resumed its original fascination, and I listened to it as to some delicious melody.

'I need only mention my cousin, Lady Gladys Dacre, and you will at once understand why I recommended you to my friend. The case of Lady Gladys, you will remember, required a delicate touch which is not always to be had in this land of England, except when those who possess the gift do us the honour to sojourn with us.'

I noticed that my glass was again filled, and bowing an acknowledgment of his compliment, I indulged in another sip of the delicious wine. I sighed, for I began to realise it was going to be very difficult for me, in spite of my disclaimer, to tell this man's friend he had stolen the money. All this time he had been sitting on the edge of the table, while I occupied a chair at its end. He sat there in careless fashion, swinging a foot to and fro. Now he sprang to the floor, and drew up a chair, placing on the table a blank sheet of paper. Then he took from the mantelshelf a packet of letters, and I was astonished to see they were held together by two bits of cardboard and a rubber band similar to the combination that had contained the folded bank notes. With great nonchalance he slipped off the rubber band, threw it and the pieces of cardboard on the table before me, leaving the documents loose to his hand.
