Of course, Peter's sister soon heard all of the boys' adventures. How they had skated over forty miles and seen rare sights on the way; how they had lost their purse and found it again. How one of the party had fallen and given them an excuse for a grand sail in an ice boat; how, above all, they had caught a robber and so, for a second time, saved their slippery purse.

"And now, Peter," said the lady when the story was finished, "you must write at once to tell the good people of Broek that your adventures have reached their height, that you and your fellow travelers have all been taken prisoners."

The boys looked startled.

"Indeed, I shall do no such thing," laughed Peter. "We must leave tomorrow at noon."

But the sister had already decided differently, and a Holland lady is not to be easily turned from her purpose. In short, she held forth such strong temptations and was so bright and cheerful and said so many coaxing and unanswerable things, both in English and Dutch, that the boys were all delighted when it was settled that they should remain at The Hague for at least two days.
