"She said she had two friends named Mary. We had little time to talk together—not many days in all. When did you see her last?"

"In November, just before she left the convent. She went and stayed with an aunt a few weeks in London, and then came here. She wrote me about you, and I recognized you from her description. That's why I——"

"Forgive me. I believe you can be of the greatest service to Mary, and to me." He glanced at Americo, who held the door open. "Let us walk in the woods, if you aren't afraid of damp. I've something important to say."

They went down the steps and out of the gate together, like old acquaintances. Peter had no longer any doubt that the "family trouble" concerned Mary; but it was easy to see that whatever it might be, Prince Vanno was on her side. Peter admired him, and burned to serve her friend.

"There has been an abominable lie told," Vanno began, as soon as they were outside his brother's gate. "I must explain to you quickly what's happened, if you're to understand. I went to Rome to tell my father of our engagement. I left Mary with my brother and sister-in-law. I had two happy letters from her. This morning I arrived here in the Rome express. I came straight to Cap Martin, expecting to find Mary. Instead I found my brother and his wife alone. My sister-in-law, I must say in justice, seemed terribly grieved at what had happened. She could or would tell me nothing. But Angelo—my brother—began some rigmarole about Mary having run away from her convent-school years ago with a man, and—but I won't repeat the story. I refused to listen. I can never forgive my brother."

"Good for you!" exclaimed the American girl. "But I see the whole thing, and you needn't even try to repeat the story. I know it without your telling. It happened to another girl with a name almost exactly like Mary's. That's how the mistake must have come about. The girl who ran away disappeared about four years ago. My Mary was at the convent till last fall. I can prove everything I say."

"Will you see my brother and his wife now, and tell them what you know?"

"With the greatest pleasure."

"Thank God you came! In another minute I should have been gone. And I don't know where to look for Mary."

"You don't know? Didn't she write? Or did she expect you to believe things against her?"
