later in the day, when it's crowded and hot. And I always used to love walking in the early morning, up in Northam.

"Well, anyhow, I got up that day about six. I knew that no stores near here would be open so early, and I decided to walk over toward the other side of town. It's a sort of poor section there, and the stores often open up quite early, so that folks can do their marketing before they go to work. It was a beautiful, cool morning, and I was quite enjoying myself when—Jan, what do you think?—I looked up, and about half a block ahead of me was a little black figure with a market-basket, hurrying along. I knew it was Miss Benedict!

"Can you imagine my surprise—and delight? I suddenly made up my mind I'd keep behind her, and go into the same store she did. There could surely be no harm in that! And by and by I saw her turn into a little grocery-shop; and a minute or two after in I walked, went to the counter, and stood right near her. There was no one in the store beside ourselves and the grocer. He looked sleepy, and was yawning while he wrapped up something for her. He asked me to 'Wait a minute, please!' which, of course, I was only too delighted to do, as it gave me a perfect right to stand close by my mysterious little neighbor and hear her speak.

"And it was right there, Janet, that I got the surprise of my life. She still wore her black veil, and it was so thick that not a bit of her face could be seen. Her dress was the most old-fashioned thing—it looked twenty years old, if not more. I don't know what sort of a voice I had expected to hear, but it was nothing in the least like what I did hear.

"I can't exactly describe it to you, Jan, but it was the most beautiful speaking voice I've ever heard in my life! It was soft, and flute-like, and so—so appealing! It somehow went straight to my heart. It made me feel as if I wanted to take care of Miss Benedict, somehow, I can't exactly explain it. Even when she was speaking of such commonplace things as butter and eggs and sugar, it was like—like music!

"Well, in a few moments she had finished, and the grocer packed her things in her basket, and she went away. I had to stay, of course, and get my oatmeal, and I didn't see her again. But being so close to her and hearing that lovely voice had changed my whole feeling about her. At first, I had just been interested and awfully curious about the whole mysterious affair, and, I'll confess, just a wee bit repelled by the account of the queer little lady and the strange way she lived. I wanted to know the explanation of the mystery, but I didn't particularly want to know her. But after that, I felt different,—sort of bewitched by that beautiful voice. I wanted to help that Miss Benedict. I wanted to do something for her, or try to make her happier, or—or something, I couldn't quite explain what. And I wanted—oh, so much!—to see her face, and know what she was like, and more about herself. Can you understand, Jan?"

"Indeed, I can. But do go on. Did you ever meet her again?"

"No, I didn't. But I've seen—and heard—something else that's strange, more strange than all the rest!"

"Tell me, quick!" demanded Janet.

"Two nights ago, I sat here by the window. It was too hot to turn on the light, but it was very dark outside. Presently I heard footsteps in the Benedict garden. They were light, quick footsteps, and sounded exactly as if some one were running about, or skipping and jumping. First I thought it must be a big dog, for it couldn't possibly have been either one of those two old ladies, running and skipping that way! And then I heard a soft humming, as if some one were singing a tune half under the breath. And then, very soon after, a door opened, and a voice called out, very softly, 'Come in, now!' And after that all was quiet. Now, Janet McNeil, I'm simply positive there's some one else in that house beside the two old ladies,—some one who hasn't been seen yet. What do you make of it?"

"You must be right," replied Janet, thoughtfully. "It couldn't be either of them running about in the garden in the dark and humming a tune. It isn't at all what they'd be likely to do. I think it must be some one else, more—more human and natural, somehow. And younger, too. But what on earth do they all keep so shut up for, and act as if they were afraid to be seen! It's the queerest thing I ever heard of. You certainly have moved next door to a 'dark-brown mystery,' Marcia!"

For the ensuing hour the girls embroidered steadily and discussed "Benedict's Folly" and its inmates in all their peculiar phases. But, turn and twist it as they might, they could find no answer to the riddle. After a while, Janet changed the subject.

"By the way, Marcia, how are you coming on with your violin practice? Have you begun taking lessons here yet? You know that was one of the principal things you folks moved to the city for,—so that you could study with the best teachers."

"Yes, I've begun with Professor Hardwick," said Marcia, "and I've practised quite hard lately. It's about all I had to do. He says I've made some progress already."

"Oh, do get your violin and play some for me!" begged Janet. "I'm just starving for some good music. I haven't heard any since you left Northam."

So Marcia obligingly went to the parlor and brought back her violin. When she had tuned it and tucked it lovingly under her chin, she sat down in the window-seat and ran her bow over the strings in a shower of liquid melody. For one so young she played astonishingly well. Janet listened, breathless, absorbed.

"Marcia dear, you have improved!" she exclaimed, as her chum stopped for a moment. "Now do play my favorite!" Marcia laid her bow on the strings once more, and slipped into the tender reverie of the "Träumerei." But before it was half finished, Janet, wide-eyed with astonishment, laid her hand on Marcia's arm.

"Look!" she breathed. Marcia followed the direction of her gaze, and turned to stare out of the window at the house opposite. And this is what she saw:

The shutter of a window on the top floor had been pushed partly open, and a face looked out,—a face with big, appealing eyes, and a frame of golden, curling hair falling all about it. Straight over at the two in the window it gazed, eager, absorbed, delighted. And then suddenly, as it detected their own interested stare, it withdrew, and the shutter was softly closed.

The two girls drew a long breath and gazed at each other.

"Janet,—what did I tell you! There is some one else in that house!" cried Marcia.

"I guess you're right!" admitted Janet, quieter, but no less excited. "But do you realize who that third person is, Marcia Brett? It isn't an old lady; it's some one just about our own age—it's a young girl!"

CHAPTER III

THE GATE OPENS

For the two ensuing days, Marcia and Janet, tense with excitement, discussed the most recently discovered inmate of "Benedict's Folly," and watched incessantly for another glimpse of the face behind the shutter. How was it, they constantly demanded of each other, that a girl of fourteen or fifteen had come to be shut up in the dreary old place? Was she a prisoner there? Was she a relative, friend, or servant? Was she free to come and go?
