“Carton,” he said confidently, “I’ll stick.”

“Good,” exclaimed the district attorney, as they fell into a conversation in low tones.

“By the way,” drawled Kennedy, “I must telephone to the office in case they need me.”

He had risen and entered the same booth.

Haddon and Carton were still talking earnestly. It was evident that, for some reason, Haddon had lost his former halting manner. Perhaps, I reasoned, the bomb episode had, after all, thrown a scare into him, and he felt that he needed protection against his own associates, who were quick to discover such dealings as Carton had forced him into. I rose and lounged back to the booth and Kennedy.

“Whom did he call?” I whispered, when Craig emerged perspiring from the booth, for I knew that that was his purpose.

Craig glanced at Haddon, who now seemed absorbed in talking to Carton. “No one,” he answered quickly. “Central told me there had not been a call from this pay-station for half an hour.”

“No one?” I echoed almost incredulously. “Then what did he do? Something happened, all right.”

Kennedy was evidently engrossed in his own thoughts, for he said nothing.

“Haddon says he wants to do some scouting about,” announced Carton, when we rejoined them. “There are several people whom he says he might suspect. I’ve arranged to meet him this afternoon to get the first part of this story about the inside working of the vice trust, and he will let me know if anything develops then. You will be at your office?”
