Before I could retort the front door-bell rang sharply. Turning quickly McKelvie walked to the safe and silently locked it. Then he spoke to Jenkins with his usual assured manner. "Tell Mason to answer the bell. And I sha'n't need you again to-day."

"Very well, sir."

As Jenkins opened the door and went out McKelvie dropped into a chair beside me.

"I wonder who that can be," he murmured, "but whoever it may be, not one sign, not one word of what we have learned."

I nodded comprehendingly, and in the pause that ensued I heard Mason shuffle to the door and fumble with the lock. Then a man's voice inquired for me. I heard an answering murmur and rose, turning toward the open study door just as Mr. Cunningham crossed the threshold.

"Mr. Davies," he said, with a smile, extending his hand. He had recovered his voice since the inquest and spoke in a rich baritone.

I gave him my hand, but not over-cordially as I said, suspiciously, "How did you know I was here?"

He laughed, not at all put out. "I called at your apartments to give you some information, and Mr. Trenton kindly told me where I could find you. He also explained your mission. A very laudable purpose. Mr. McKelvie, I presume?" turning toward my companion.

"I beg your pardon," I said stiffly, for I was ashamed of my unjust suspicion, which had its inception in the fact that he was the dead man's lawyer, and as such prejudiced against Ruth, and introduced the two men.

McKelvie, who had also risen at the lawyer's entrance, and who was standing with his hands behind his back, affected not to see Cunningham's extended hand and merely nodded. Annoyed at his incivility, and seeing that Cunningham frowned angrily, I hastened to make the peace.
