Mademoiselle of Monte Carlo by William le Queux

Late on Thursday night Dorise and her mother were driving home from Lady Strathbayne's, in Grosvenor Square, where they had been dining. It was a bright starlight night, and the myriad lamps of the London traffic flashed past the windows as Dorise sat back in silence.

She was tired. The dinner had been followed by a small dance, and she had greatly enjoyed it. For once, George Sherrard, her mother's friend, had not accompanied them. As a matter of fact, Lady Strathbayne disliked the man, hence he had not been invited.
