“The chief detective came close up to me, put his mouth to my ear, and whispered, ‘Le drapeau blanc!’”

This instantaneous action, which I had considered necessary for my own protection, turned out to be the best possible course for the safety of the millions. Now I had redeemed my promise to Madame Humbert, by admitting that I was in possession of the lost treasure, and I waited confidently for the person who should come to claim it.

Exactly two days afterwards I was surprised by a visit from M. Rattache, whom I had not seen for some time, a slight coolness having resulted from his abortive efforts to surprise my secret.

The chief detective, instead of taking the chair I offered him, came close up to me, put his mouth to my ear, and whispered: ‘Le drapeau blanc!

The white flag! Is there any English reader who does not know that in France the white flag signifies the ancient standard of the Valois and the Bourbons—the inseparable emblem of Legitimist royalty, which the Comte de Chambord refused to exchange for the Revolutionary tricolor, even to obtain the throne?

I stared at M. Rattache, confounded to find in the head of the Republican police the confidential agent of the Monarchists.

He enjoyed my astonishment for a minute in silence. Then he said aloud—

‘Now, my dear V——, perhaps you will reveal to me the secret of that hiding-place which has baffled the efforts of my best men for so long.’

I smiled quietly as I took up my hat.

‘On first receiving this fund I simply put the notes and bills in a registered parcel and sent it to my agent in Brussels, with instructions to put it in a fresh cover and send it to and fro through the post till further notice. But on finding that you were interested in my correspondence I naturally adopted another plan. I will take you at once to the spot where I have deposited these millions, which I shall not be sorry to get rid of.’
