The Gates of Dawn by Fergus Hume — Read

For the space of a minute, or it might be more, they looked at one another -- Miss Linisfarne at Dan, he and Meg at Miss Linisfarne. It was so contrary to her usual custom to thus show herself to a stranger, that Meg might well be excused for being tongue-tied with astonishment. The languid creature whom Meg knew and pitied had disappeared as by magic, and in her place stood a bright-eyed, cheek-flushed being, who had regained for the moment the lost loveliness of her prime. Unable to guess the reason of this rejuvenescence, Meg could only look at her benefactress with parted lips and amazed eyes.

Miss Linisfarne took no heed of her presence, but examined Dan in a leisurely manner, as though he were as indifferent to her regard as was Sir Alurde in his frame behind. Man of the world as Dan was, the eager scrutiny of this woman made him vaguely resentful, and he was amazed at the lack of delicacy which could permit her to signify so openly her admiration for a stranger. It seemed an insult to Meg that she should look at him with such brazen assurance; and, indifferently as he returned her gaze, he felt indignant at her demeanour. Meg was the first of the trio to break silence. She mistook Miss Linisfarne's examination of Dan for anger at his intrusion, and hastened to excuse him.
