He had, in fact, been enough at her beck and call to make her the envy of a young society with whom the splendid Englishman promised to become the rage, and not enough to silence or wholly discourage other claimants on his time.
This no doubt accounted for the fact that the two charming Bostonians, Mrs.Maddison and her daughter, who had but lately arrived in Washington and made acquaintance with Roger Barnes, were still evidently in ignorance of what was going on.

They were not initiated.

They had invited young Barnes in the innocence of their hearts, without inviting Daphne Floyd, whom they did not previously know.

And the young man had seen fit to accept their invitation.

Mrs.Verrier's advice not to make Roger Barnes "too important" had called up a flash of colour in the girl's cheeks.
