Instantly, Craig read from the startled look on Elaine's face that something dreadful had happened.

"Why—what's the matter?" he asked, solicitously.

"A—another letter—from the Clutching Hand!" she exclaimed breathlessly. "Mr. Bennett was calling on me, when this note was brought in. We both thought we'd better see you at once about it and he was kind enough to drive me here right away in his car."

Craig took the letter and we both read, with amazement:

"Are you an enemy of society? If not, order Craig Kennedy to leave the country by nine o'clock to-morrow morning. Otherwise, a pedestrian will drop dead outside his laboratory every hour until he leaves."

The note was signed by the now familiar sinister hand, and had, added, a postscript, which read:

"As a token of his leaving, have him place a vase of flowers on his laboratory window to-day."

"What shall we do?" queried Bennett, evidently very much alarmed at the threat.

"Do?" replied Kennedy, laughing contemptuously at the apparently futile threat, "why, nothing. Just wait."
