“Well, who wouldn’t be? That bill was on the table in my bedroom, and Martha was in the room after I was. And when I came home, it was gone.”

“You were very careless to leave it on the table.”

“No, I wasn’t. I didn’t want to take it with me, so I stuck it behind a picture that stands on the table. Nobody would have seen it, but Martha knew it was there; she was in the room when I put it there.”

“Maybe it blew off the table.”

“It might have, but I’ve looked all over the room everywhere.”

Dorothy sat silent. She hadn’t wanted Martha to come, but Betty had coaxed her into it, and this was the result.

“Well,” she said at last, “I’m going to tell Betty about it, anyway. I know she’ll think as I do, that Martha couldn’t have done such a thing.”

“No, don’t tell Betty.”

“Yes, you will tell Betty, too!” said a voice, and looking up, the two girls saw Betty looking at them. The boat had drifted near shore, and Betty beckoned to them to come in.

“Now, you tell me what it’s all about,” she said, as they landed. “I’m not going to be kept out of it any longer.”
