In fact, they parted rather abruptly, which was wise.
All had been said that could be said, and Lambert had given his promise to share the burden with Agnes by acting the part of a lover who had never really been serious.

But it did not do to discuss details, as these were too painful, so the woman hurried away without a backward glance, and Lambert, holding his heart between his teeth, returned to the studio.

Neither one of the two noticed Chaldea crouching amongst the flowers.

Had they been less pre-occupied, they might have done so; as it was she escaped observation.
As soon as the coast was clear, Chaldea stole like a snake along the ground, through the high herbage of the garden, and beyond the circle of the mysterious monoliths.

Even across the lawns of the glade did she crawl, so as not to be seen, although she need not have taken all this trouble, since Lambert, with a set face and a trembling hand, was working furiously at a minor picture he utilized to get rid of such moods.
