The incident was, no doubt, a disconcerting one for them both, because from that moment their manner changed. The gambling within the big rotunda had no interest for either of them, and a quarter of an hour later Madame, with her peculiar rasping voice, said—

“Pierrette, ma chère, it is time we returned,” to which the girl acquiesced without comment.

Therefore I took them along to Beaulieu and deposited them at the door of their hotel.

Having seen them safely inside, I turned the car round and went back to Nice.

It was then about ten o’clock, but on the night of a Carnival ball the shops in the Avenue de la Gare are all open, and the dresses necessary for the ball are still displayed. Therefore, having put the car into the garage again, I purchased a pierrot’s kit similar to that worn by the reveller, a black velvet loup, or mask, put them on in the shop, and then walked along to the Casino.

Till near midnight I went among that mad crowd, but could not recognise him. He might, I reflected, be by that hour in such a state of intoxication as to be unable to come to the ball at all.

Suddenly, however, as I was brushing past two masked dancers who were standing chatting at one of the doors leading from the Casino into the theatre where the ball was in progress, one of them exclaimed with a French accent—
