"I wouldn't dare tell her now, anyway," returned Amy, with a twinkle. "Methinks it might very easily become my death warrant."

"How so?" queried Mollie with interest—or perhaps it might be said, Mollie's back expressed interest. For Mollie's back could express, Grace had once said, "more emotions in a minute than most people's faces could in a year." And, riding as they so often did, in full view of that expressive back, the girls had come to interpret its owner's emotions correctly in nine cases out of ten. So now they were able to detect a very quickened interest.

"Why," Amy explained naïvely, "it's barely possible that I've left something to Mollie, too, isn't it?"

"Barely," agreed Mollie dryly.

"Well," Amy chuckled, "then what would be easier than for Mollie to precipitate an accident, dash my brains out against some convenient tree, and then brazenly protest all innocence in the murder."

"Nothing," said Mollie, with the same dryness of intonation, "except the bare possibility of dashing my own brains out in the transaction."

"Oh, well, it could be fixed," said Amy with confidence.

"Do you really think so?" Mollie's back once more betrayed a lively interest, and the girls chuckled. "Suppose you tell me about it."

"And sign my own death warrant?" returned Amy plaintively. "Goodness, you must think I'm foolisher than I am."

"Impossible," retorted Mollie and once more Amy sighed and folded her hands resignedly in her lap.
