“God!”

The panic re-entered Dr. MacArthur’s eyes and Higgins took advantage of it.

“You are right about time, Doctor. It’s everything. To save time I must have every atom of knowledge which you have. Last night I hoped to work independently, but now....”

He leaned forward and shot his gimlet gray eyes into the horror stricken ones of MacArthur.

“Is the man everybody but you suspects, young Sterling?”

MacArthur’s groan was evidence.

“Well, I thought so. Last night you suggested I question him last on account of his father.”

MacArthur’s fight seemed suddenly to return and he shot back:

“This morning I demand it. His father will be dead by midnight. I appreciate your position, but I must ask you to respect my wishes. Have you given up the idea that Bear Sterling is implicated?”

“No, sir. But we cannot await another murder to clear him.”
