Leaning forward a little, she rested one arm farther on the table, which was covered with a light cloth, and drew the latter toward her with a slight movement of her elbow until a wider strip of it overhung the edge. She could not warn her hostess in the hearing of the man, when she had only suspicion to act on, but she was determined that he should not discover Winthrop's whereabouts if she could help it. Nevis's eyes, as she noticed, were fixed on the envelope, but he was evidently still too far off to read the postmark, and she waited another moment, watching him with mingled disgust and anger at the means he used.
In the meanwhile it was clear that Mrs. Calvert had no suspicion of what was going forward, for there was nothing to show that Alison's heart was beating a good deal faster than it generally did, or that the man was conscious of a vindictive satisfaction. His approach had been ostensibly careless, and there was only a faintly suggestive hardness in his eyes. The girl sat very still, and if her face was a little more intent than usual her hostess did not notice it.
Alison fancied that she heard a sound outside the window again, but she paid no heed to it, and as Nevis was about to lay his hand on the table and lean over it she moved her elbow sharply. The next moment the cloth slid down into a heap on the floor, and the letter disappeared.
Nevis closed one hand viciously, but he opened it again immediately as he turned to Alison. The man was quick, and held himself well in hand, and she felt a certain satisfaction in outwitting him, for it was clear that he had not suspected her of having any motive for jerking the cloth off.
"Am I accountable for the accident?" he asked.
"No," replied Alison; "it was my fault."
The danger, however, was not quite over. Alison quietly felt with one little, lightly shod foot beneath the cloth, part of which had caught and rested on her dress. Her shoe touched something that seemed harder than the soft fabric, and she contrived to draw it toward her.
"You knocked a letter off the table," said Nevis. "It must have fallen somewhere near. Permit me."
He stooped to pick up the cloth, and Alison saw that Mrs. Calvert was at last uneasy. It was obvious that she did not wish Nevis to lay his hands on the envelope. He raised the cloth, and after a glance beneath it moved a pace or two and shook it vigorously, but nothing fell out, and Alison quietly pushed back her chair.
"It's here beneath my skirt."
