In the glorious sundown glinting across the river, and rendering it a rippling flood of gold, Max and Marion were seated in the long upstairs room of that old-fashioned riparian inn, the “London Apprentice,” at Isleworth, taking their tea at the open window.

Before them was the green ait, with the broad, tree-fringed river beyond, a quiet, peaceful old-world scene that, amid the rapidly changing metropolitan suburbs, remains the same to-day as it has been for the past couple of centuries or so.

They always preferred that quiet, old-fashioned upstairs room—the club-room, it was called—of the “London Apprentice,” at Isleworth, to the lawns and string bands of Richmond, the tea-gardens of Kew, or the pleasures of Eel Pie Island.

That long, silent, old, panelled room with its big bow-window commanding a wide reach of the river towards St. Margaret’s was well suited to their idyllic love. They knew that there they would at least be alone, away from the Sunday crowd, and that after tea they could sit at the window and enjoy the calm sundown.

The riverside at Isleworth does not change. Even the electric trams have passed close by it on their way to Hampton Court from Hammersmith but they have not modernised it. The old square-towered church, the row of ancient balconied houses, covered with tea-roses and jasmine, and the ancient waterman’s hostelry, the “London Apprentice,” are just the same to-day as they have ever been in the memory of the oldest inhabitant; and the little square in the centre of the riverside village is as silent and untrodden as in the years when Charles II loved to go there on his barge and dine in that very room at the inn, and when, later, David Garrick and Pope sang its praises.

Max and his well-beloved had finished their tea, and, with her hat and gloves off, she was lying back in a lounge chair in the deep bay window, watching the steamer Queen Elizabeth, with its brass band and crowd of excursionists, slowly returning to London. Near her he was seated, lazily smoking a cigarette, his eyes upon her in admiration, but still wondering, as he always wondered.

The truth concerning Maud Petrovitch had not been told.

He was very fond of the Doctor. Quiet, well-educated, polished, and pleasant always, he was, though a foreigner, and a Servian to boot, the very essence of a gentleman. His dead wife had, no doubt, influenced him towards English ways and English thought, while Maud herself—the very replica of his lost wife, he always declared—now held her father beneath her influence as a bright and essentially English girl.

The disappearance of the pair was an enigma which, try how he would, he could not solve. His efforts to find Rolfe had been unavailing, and Marion herself had neither seen nor heard from him. At Charlie’s chambers his man remained in complete ignorance. His master had left for Servia—that was all.

Max had been trying in vain to lead the conversation again up to the matter over which his mind had become so much exercised; but, with her woman’s keen ingenuity, she each time combated his efforts, which, truth to tell, only served to increase his suspicion that her intention was to shield herself behind her friend.
