A MYSTERIOUS LETTER 

In the morning mail Gus Plum received a letter postmarked London which he read with much interest. Then he called on Dave. 

"I've just received a letter I want you to read," he said. "It is from Nick Jasniff, and he mentions you." And he handed over the communication. 

It was a long rambling epistle, upbraiding Plum roundly for "having gone back on him," as Jasniff put it. The writer said he was now "doing Europe" and having a good time generally. One portion of the letter read as follows: 

"The authorities needn't look for me, for they will never find me. I struck a soft thing over here and am about seventy pounds to the good. Tell Dave Porter I could tell him something he would like to hear--about his folks--but I am not going to do it. I don't think he'll meet that father of his just yet, or that pretty sister of his either. She'd be all right if she didn't have such a lunkhead of a brother. Tell him that some day I'll square up with him and put him in a bigger hole than he got me into. If it wasn't for him I wouldn't have to stay away as I'm doing--not but what I'm having a good time--better than grinding away at Oak Hall." 

As may be imagined, Dave read this letter with even greater interest than had Gus Plum. What was said about his father and sister mystified him.

CHAPTER IV. 

Signor Andrea D'Arbino, searching vainly through the various rooms in the palace for Count Fabio d'Ascoli, and trying as a last resource, the corridor leading to the ballroom and grand staircase, discovered his friend lying on the floor in a swoon, without any living creature near him. Determining to avoid alarming the guests, if possible, D'Arbino first sought help in the antechamber. He found there the marquis's valet, assisting the Cavaliere Finello (who was just taking his departure) to put on his cloak. 

While Finello and his friend carried Fabio to an open window in the antechamber, the valet procured some iced water. This simple remedy, and the change of atmosphere, proved enough to restore the fainting man to his senses, but hardly--as it seemed to his friends--to his former self. They noticed a change to blankness and stillness in his face, and when he spoke, an indescribable alteration in the tone of his voice. 

"I found you in a room in the corridor," said D'Arbino. "What made you faint? Don't you remember? Was it the heat?" 

Fabio waited for a moment, painfully collecting his ideas. He looked at the valet, and Finello signed to the man to withdraw. 

"Was it the heat?" repeated D'Arbino. 

"No," answered Fabio, in strangely hushed, steady tones. "I have seen the face that was behind the yellow mask." 

"Well?" 

"It was the face of my dead wife." 

"Your dead wife!" 

"When the mask was removed I saw her face. Not as I remember it in the pride of her youth and beauty--not even as I remember her on her sick-bed--but as I remember her in her coffin."

My name is Sandra. Let me tell you the story of the best meal I ever had. 

I was sitting on the school bench outside Springfield Elementary School, waiting to pick up my granddaughter. She is a real cutie, and I am very proud of her grades. To pass the time, I played my triangle. In my youth, I was a triangle player in a large New York band, the Black Triangles. We all wore full black costumes every time we played. 

"What lovely triangle music! You make me think of a friend I had once upon a time." 

A strange lady, about my age, was standing next to me, talking! She was holding a trumpet. It turns out the strange lady was my old friend and Black Triangle trumpet player Matilda. We hadn't seen each other since New York. Matilda told me she wanted to keep in touch, but couldn't remember what I looked like! We found out that all we remembered were the black costumes we always wore! It turns out; Matilda was also there to pick someone up from school. 

"Well, Sandra, why don't you join me and my grandson for lunch? There is a lovely Thai place right down the road.' 

We went there with my granddaughter and her grandson, and had a delicious meal. Our grandchildren got married 15 years later.
