That was tactful , and indeed his courtesy and pleasant words during her first brief meeting with him in the Embankment Hotel had conveyed the same favorable impression .

Her whole-souled enjoyment of novel surroundings was an asset for the outlay of his two hundred pounds , and he had fully and finally excused that piece of extravagance until he caught sight of Bower strolling along the platform with the easy confidence of one who knew exactly whom he would meet and how he would account for his unbidden presence . Spencer at once suspected the man 's motives , not without fair cause .
