The Vanished Messenger by E. Phillips Oppenheim

The beautiful but somewhat austere front of St. David's Hall seemed, in a sense, transformed, as Hamel and his companion climbed the worn grey steps which led on to the broad sweep of terrace. Evidently visitors had recently arrived. A dark, rather good-looking woman, with pleasant round face and a ceaseless flow of conversation, was chattering away to Mr. Fentolin. By her side stood another woman who was a stranger to Hamel -- thin, still elegant, with tired, worn face, and the shadow of something in her eyes which reminded him at once of Esther. She wore a large picture hat and carried a little Pomeranian dog under her arm. In the background, an insignificant-looking man with grey side-whiskers and spectacles was beaming upon everybody. Mr. Fentolin waved his hand and beckoned to Hamel and Esther as they somewhat hesitatingly approached.

"This is one of my fortunate mornings, you see, Esther! " he exclaimed, smiling. "Lady Saxthorpe has brought her husband over to lunch. Lady Saxthorpe," he added, turning to the woman at his side, "let me present to you the son of one of the first men to realise the elusive beauty of our coast. This is Mr. Hamel, son of Peter Hamel, R. A. -- the Countess of Saxthorpe."
