“Well, I’m not cold by any means,” replied Pierre, as he sat at her feet wiping his forehead.

She laughed, and answered that she had never before seen him with such a colour. Then they began to talk like children, like two young friends, finding a source of gaiety in the most puerile things. She was somewhat anxious about his health, however, and would not allow him to remain in the cool shade, as he felt so very warm. In order to tranquillise her, he had to change his place and seat himself with his back to the sun. Then a little later he saved her from a large black spider, which had caught itself in the wavy hair on the nape of her neck. At this all her womanly nature reappeared, and she shrieked with terror. “How stupid it was to be afraid of a spider!” she exclaimed a moment afterwards; yet, in spite of her efforts to master herself, she remained pale and trembling.

Silence at last fell between them, and they looked at one another with a smile. In the midst of that delicate greenery they felt drawn together by frank affection—the affection of brother and sister, so it seemed to them. It made Marie very happy to think that she had taken an interest in Pierre, and that his return to health was largely her own work. However, their eyes never fell, their hands never met, even as they sat there toying with the grass, for they were as pure, as unconscious of all evil, as were the lofty oaks around them.

At last Marie noticed that time was flying. “You know that they expect us back to lunch,” she exclaimed. “We ought to be off.”

Thereupon they rose, wheeled their bicycles back to the highway, and starting off again at a good pace passed the Loges and reached Saint-Germain by the fine avenue which conducts to the château. It charmed them to take their course again side by side, like birds of equal flight. Their little bells jingled, their chains rustled lightly, and a fresh breeze swept past them as they resumed their talk, quite at ease, and so linked together by friendship that they seemed far removed from all the rest of the world.

They took the train from Saint-Germain to Paris, and on the journey Pierre suddenly noticed that Marie’s cheeks were purpling. There were two ladies with them in the compartment.

“Ah!” said he, “so you feel warm in your turn now?”

But she protested the contrary, her face glowing more and more brightly as she spoke, as if some sudden feeling of shame quite upset her. “No, I’m not warm,” said she; “just feel my hands.... But how ridiculous it is to blush like this without any reason for it!”

He understood her. This was one of those involuntary blushing fits which so distressed her, and which, as Mère-Grand had remarked, brought her heart to her very cheeks. There was no cause for it, as she herself said. After slumbering in all innocence in the solitude of the forest her heart had begun to beat, despite herself.

Meantime, over yonder at Montmartre, Guillaume had spent his morning in preparing some of that mysterious powder, the cartridges of which he concealed upstairs in Mère-Grand’s bedroom. Great danger attended this manufacture. The slightest forgetfulness while he was manipulating the ingredients, any delay, too, in turning off a tap, might lead to a terrible explosion, which would annihilate the building and all who might be in it. For this reason he preferred to work when he was alone, so that on the one hand there might be no danger for others, and on the other less likelihood of his own attention being diverted from his task. That morning, as it happened, his three sons were working in the room, and Mère-Grand sat sewing near the furnace. Truth to tell, she did not count, for she scarcely ever left her place, feeling quite at ease there, however great might be the peril. Indeed, she had become so well acquainted with the various phases of Guillaume’s delicate operations, and their terrible possibilities, that she would occasionally give him a helping hand.
