Paul’s voice settled the question: the city was too full of pilgrims for any pleasure to be had within the walls; why not take advantage of the pleasant weather to drive out to the monastery of Tre Fontane? But the matter did not eventually arrange itself as happily as he had hoped, since he found himself in one carriage and Marcia in the other. At the monastery the monks were saying office in the main chapel when they arrived, and they paused a few minutes to listen to the deep rise and fall of the Gregorian chant as it echoed through the long, bare nave. The dim interior, the low, monotonous music, the unseen monks, made an effective whole. Paul, awake to the possibilities of the occasion, did his best to draw Marcia into conversation, but she was tantalizingly unresponsive. The guide-book in Mrs. Royston’s hands and the history of the order appeared to absorb her whole attention. Fortune, however, was finally on his side. Mrs. Royston elected to stop, on their way back to the city, at St. Paul’s without the Walls, and the whole party once more alighted. Within the basilica, Mrs. Royston, guide-book in hand, commenced her usual conscientious inspection, while Eleanor and the young Frenchman strolled about, commenting on the architecture. Margaret had heard that one of the mosaic popes in the frieze had diamond eyes, and she was insistently bent on finding him. Marcia and Paul followed her a few minutes, but they had both seen the church many times before, and both were at present but mildly interested in diamond-eyed popes. The door of the cloisters stood ajar, and they presently left the others and strolled into the peaceful enclosure with its brick-flagged floor and quaintly twisted columns. It was tranquil and empty, with no suggestion of the outside world. They turned and strolled down the length of the flagging, where the shadow of the columns alternated with gleaming bars of sunshine. The sleepy, old-world atmosphere cast its spell about them; Marcia’s tantalizing humour and Paul’s impatience fell away. They walked on in silence, until presently the silence made itself awkward and Marcia began to talk about the carving of the columns, the flowers in the garden, the monks who tended them. Paul responded half abstractedly, and he finally broke out with what he was thinking of: a talk they had had that afternoon several weeks before in the Borghese gardens.
