Duperré was certainly nothing if not ingenious and his sang-froid had saved us all from terms of imprisonment.

Madame replaced the valuable feathers in her hat, and when we arrived at Fontainebleau we drove at once to the Hôtel de France, opposite the palace, where we took an excellent déjeuner in a private room.

And before we left, Duperré had disposed of Lady Norah’s jewels at a very respectable figure, which the sly old receiver paid over in thousand-franc notes.

I marveled at my companion’s ingenuity, whereupon he laughed airily, replying:

“When ‘The Golden Face’ arranges a coup it never fails to come off—I assure you. The police have to be up very early to get the better of him. His one injunction to all of us is that we shall be ready at all times to show clean hands—as we have to-day! But let’s get away, Hargreave—back to London, I think, don’t you?”

The whole adventure mystified and bewildered me. It was a mystery which, however, before long, was to be increased a hundredfold. Alas! that I should sit here and put down my guilt upon paper!
