All three were now examining Mary's "Pet" closely, getting innocent little flies in line for the scent, which might attract them, and otherwise enjoying the novelty.

"Is it valuable?" asked Madaline, noting the rare crimson color inside the cup.

"Yes, I think this one is, but I like it more than any of the others because I raised it myself. But when you come to our place I will show you our wonders," she offered.

"Is that why you always gather roots?" asked Cleo.

"Not exactly," Mary replied, just a trace of her cloud threatening to darken her face. "But I can't talk about all of it now. I am sure it must be time to go visit Grandie. Do you suppose we may go soon?" This question was addressed to Cleo.

"I'll see if Auntie has finished," Cleo answered, running back to the house. Mary arranged a safer place for her pitcher plant, out where insects might find its fatal honey. Then, gathering up the basket, she, with the others, hurried back to the veranda. They found the three men just leaving, and as Mrs. Dunbar smiled frankly it was easy to guess the result of their interview had not been altogether unpleasant.

Michael had also been in the conference, and he delayed a moment to speak privately with Mrs. Dunbar.

"How is Shep?" she asked aside, so that her voice could not reach the girls.

"Coming around all right," replied the man, gladly. And he brought in a clew to his enemy. "Step inside and look at this." He took from his pocket a handkerchief. It was yellow in color, silk in texture, and was bordered with drawn work. Mrs. Dunbar examined it closely.

"Foreign, of course," she replied. "Those people seem to be pretty well organized. Take care of that, Michael; we may easily match it up later. Now I have to see what we are going to do about Professor Benson. The girls seem to need very little assistance, but we must watch closely to see they make no mistakes. This is more of a plot than I supposed, but our police are glad to get on the track of these men. Here are the children. If they ask for Shep make some reasonable excuse."
