"But why?"

"How can I tell? I believe it has something to do with that horrid man I told you of. You sent a letter upstairs this morning. I met Joseph on the landing, and took the letter to her myself. Why shouldn't I look at the postmark? Where was the harm in saying to her, 'A letter, mamma, from Wurzburg'? She looked at me as if I had mortally offended her—and pointed to the door, and locked herself in. I have knocked twice, and asked her to forgive me. Not a word of answer either time! I consider myself insulted. Let me go to Fritz."

I made no attempt to detain her. She had set those every-ready suspicions of mine at work again.

Was the letter which I had sent upstairs a reply to the letter which Minna had seen her mother writing? Was the widow now informed that the senile old admirer who had advanced the money to pay her creditors had been found dead in his bed? and that her promissory note had passed into the possession of the heir-at-law? If this was the right reading of the riddle, no wonder she had sent her daughter out of the room—no wonder she had locked her door!

My aunt wasted no time in expressions of grief and surprise, when she was informed of Mr. Engelman's state of health. "Send the widow here directly," she said. "If there is anything like a true heart under that splendid silk dress of hers, I shall write and relieve poor Engelman by to-night's post."

To confide my private surmises, even to my aunt, would have been an act of inexcusable imprudence, to say the least of it. I could only reply that Madame Fontaine was not very well, and was (as I had heard from Minna) shut up in the retirement of her own room.

The resolute little woman got on her feet instantly. "Show me where she is, David—and leave the rest to me."

I led her to the door, and was dismissed with these words—"Go and wait in my room till I come back to you." As I retired, I heard a smart knock, and my aunt's voice announcing herself outside—"Mrs. Wagner, ma'am, with something serious to say to you." The reply was inaudible. Not so my aunt's rejoinder: "Oh, very well! Just read that letter, will you? I'll push it under the door, and wait for an answer." I lingered for a minute longer—and heard the door opened and closed again.

In little more than half an hour, my aunt returned. She looked serious and thoughtful. I at once anticipated that she had failed. Her first words informed me that I was wrong.

"I've done it," she said. "I am to write to Engelman to-night; and I have the widow's permission to tell him that she regrets her hasty decision. Her own words, mind, when I asked her how I should put it!"
