“And we worked so hard planting those bulbs,” Jane wailed. “It’s the meanest trick yet.”

Miss Gordon spoke quietly.

“Mrs. Gabriel, I think, is after something more vital than tulip bulbs.”

“I think so too,” agreed Miss Mohr quickly. “Peter has told me of his suspicions that a ring may be operating—”

Now the Brownies were quite bewildered by the talk, not understanding what the two young women meant.

“Must we let that dreadful Mrs. Gabriel ruin our flower bed?” demanded Jane.

“No, indeed,” replied Miss Mohr. “I intend to call Peter Van Der Lann and the police.”

“The police?” gasped Vevi. She had not thought of having Mrs. Gabriel arrested.

“We must hurry,” urged Miss Gordon, peering out the window again.

While the teacher and the Brownie Scouts kept watch, Miss Mohr telephoned the police station. Then she called Hanny’s uncle at Windmill Farm.
