"You have no idea who could have sent such a note?" queried Craig, "or to whom it might refer?"
He glanced at Norton, then at us. It was clear that some sort of suspicion had flashed over him. "No," he said quickly, "I know no one who could have sent it."
"But whom does it mean?" asked Kennedy, holding him to the part that he avoided.
The young man shrugged his shoulders. "She has many friends," he answered simply.
"Yes," persisted Kennedy, "but few against whom she might be warned in this way. You do not think it is Professor Norton, for instance—or myself?"
"Oh, no, no—hardly," he replied, then stopped, realizing that he had eliminated all but Lockwood, Whitney, and himself.
"It could not be Mr. Lockwood?" demanded Craig.
"Who sent it?" he asked, looking up.
"No—whom it warns against."
De Moche had known what Kennedy meant, but had preferred to postpone the answer. It was native never to come to the point unless he was forced to do so. He met our eyes squarely. He had not the penetrating power that his mother possessed, yet his was a sharp faculty of observation.
