It seemed to Lydia that she had been abroad for years, though in reality she had been three days in Cap Martin, when Mr. Marcus Stepney became a regular caller.

Even the most objectionable people improve on acquaintance, and give the lie to first impressions.

Mr. Stepney never bored her. He had an inexhaustible store of anecdotes and reminiscences, none of which was in the slightest degree offensive.

"Father is going to investigate," said Jean, "and the water really is the warmest place," and with that she fell sideways into the blue sea like a seal, dived down into its depths, and presently Lydia saw her walking along the white floor of the ocean, her little hands keeping up an almost imperceptible motion. Presently she shot up again, shook her head and looked round, o............
