Suspense, Volume II by Henry Seton Merriman

Brenda left Mrs. Wylie at eleven o'clock, merely walking away from the door of Suffolk Mansions without wrap or luggage. She did not know whether she was being watched or no, but her plans were so simple, and yet so cunning, that the question gave her little trouble. Detection was impossible. Trist had seen to that, and his strategy had been the subject of some subdued laughter the night before, because Brenda complained that she felt like an army. He had unconsciously dictated to her, in his soft, suggestive way, and so complete were his instructions, so abject the obedience demanded, that there was some cause for her laughing dissatisfaction. With intelligence, education, experience, reading, and money it is no difficult matter to evade the closest watcher, and Trist was not at all afraid of such means as lay at Captain Huston's disposal for tracing the hiding-place of his wife.

When Mrs. Wylie found herself left alone, she proceeded placidly to await further events. She was convinced that, sooner or later, the husband of her protégée would appear. Whether this questionable honour would be conferred with bluster and righteous indignation, or with abject self-abuse, remained to be seen. Neither prospect appeared to have the power of ruffling the lady's serene humour. The morning newspaper received its usual attention, and subsequently there were some new books to be cut and glanced at. Lunch had already been ordered -- lunch for two, and something rather nice, because Theo Trist had invited himself to partake of the lone widow's hospitality.
