"What were they going to do?" asked Ricardo.

Hanaud shrugged his shoulders.

"It is not pretty—what they were going to do. We reach the garden in our launch. At that moment Hippolyte and Adele, who is most likely Hippolyte's wife, are in the lighted parlour on the basement floor. Adele is preparing her morphia-needle. Hippolyte is going to get ready the rowing-boat which was tied at the end of the landing-stage. Quietly as we came into the bank, they heard or saw us. They ran out and hid in the garden, having no time to lock the garden door, or perhaps not daring to lock it lest the sound of the key should reach our ears. We find that door upon the latch, the door of the room open; on the table lies the morphia-needle. Upstairs lies Mlle. Celie—she is helpless, she cannot see what they are meaning to do."

"But she could cry out," exclaimed Ricardo. "She did not even do that!"

"No, my friend, she could not cry out," replied Hanaud very seriously. "I know why. She could not. No living man or woman could. Rest assured of that!"

Ricardo was mystified; but since the captain of the ship would not show his observation, he knew it would be in vain to press him.

"Well, while Adele was preparing her morphia-needle and Hippolyte was about to prepare the boat, Jeanne upstairs was making her preparation too. She was mending a sack. Did you see Mlle. Celie's eyes and face when first she saw that sack? Ah! she understood! They meant to give her a dose of morphia, and, as soon as she became unconscious, they were going perhaps to take some terrible precaution—" Hanaud paused for a second. "I only say perhaps as to that. But certainly they were going to sew her up in that sack, row her well out across the lake, fix a weight to her feet, and drop her quietly overboard. She was to wear everything which she had brought with her to the house. Mlle. Celie would have disappeared for ever, and left not even a ripple upon the water to trace her by!"

Ricardo clenched his hands.

"But that's horrible!" he cried; and as he uttered the words the car swerved into the drive and stopped before the door of the Hotel Majestic.

Ricardo sprang out. A feeling of remorse seized hold of him. All through that evening he had not given one thought to Harry Wethermill, so utterly had the excitement of each moment engrossed his mind.
