“Roulette records,” he thought again, “the same idiotic obsession.”

Soon she rose; and having finished his tea, he sauntered idly after her. He thought she was going to re-enter the Casino; but instead she turned up-hill in the direction of the town. He saw her climb the steps of the Church and enter its swinging door.

After waiting a little, he, too, entered. He found her seated in the cool dusk, her slim hands crossed and her eyes closed. Whether she was sleeping or praying he could not tell. He watched her for a while; then as she continued to sit immovable he went away.

4.

Hugh had found that the strange theatrical charm of Monte Carlo was most obvious after dark, and he never tired of wandering through the still gardens, breathing the delicious freshness of the air. Whichever way he looked a picture formed itself. The tiny paths were like coral ribbands on a gown of green, embroidered with pansy patterns of crimson, violet and silver. Under the lamps the blades of the patrician palms shone like swords. There were lace-screens of translucent green, rich velvet dusks, and sudden surprises of silver. The fountain sprayed diamonds into the dark pool, from which came the ruddy flash of gold-fishes; the roses climbed the palms as if to reach the light.

That evening he took a seat on the terrace. He heard below him the soft crooning of the sea, and felt its cool breath. Behind him was starlight and softly luminous mountains; in front, deep violet space ... mystery, immensity.

A small form came slowly along the terrace. As it drew near he saw it was the strange girl who was always alone. Once or twice she stopped, looking out over the balustrade to the sea. As she passed him he saw that her face had the vacant look of a sleep-walker. She sank on a bench, and took a glazed note-book from her bag. As she looked at it she sighed with weariness. Her head drooped forward and she slept.

Another dark form drew near her, the furtive figure of a man. Softly he sat down on the same bench and seemed to edge nearer and nearer.

Hugh rose, making unnecessary noise. The man, with a start, glanced his way and swiftly disappeared. Yet in that flash Hugh had recognized him; it was that sinister individual, the Rat.

Hugh went for a walk in the Condamine and did not return until half past ten. He glanced down to the terrace; hunched on the bench, a solitary figure, the girl still slept.
