Next, “Cut for it!” Agatha heard a voice exclaim—a deep voice. But, strangely enough, the gipsies did not attempt to get away. They stood and grinned at the little crowd that had gathered.

Mr. McVicar sprang to Agatha’s side. He was panting and—could it be true?—gurgling what sounded like words!

“I did not bite him,” protested the man-gipsy. “It was the monkey.”

“Where is that monkey?” shouted the woman-gipsy. “Say, you fellows, hunt him up. If we lose him we’re out twenty plunks.”

Three or four of the onlookers scattered in different directions, searching.

“Shut up, you she-devil!” ordered the second officer.
