Hanny shook her head. She had been made very uneasy by so many questions about her uncle.
“I’ll drop around later when Mr. Van Der Lann is at home,” the FBI man said to reassure her. “He may be able to help me.”
Very shortly the stranger left without explaining why he had come to Windmill Farm or what he was investigating. Hanny, however, was very worried.
“FBI men always arrest people, don’t they?” she remarked nervously to Vevi. “Why would he come here?”
“Maybe he thinks your uncle has done something wrong.”
“Not Uncle Peter,” declared Hanny. “No, it is about Mrs. Gabriel, I think. Oh, dear, I wish my uncle were here. I’m worried.”
By this time it was quite late. Mr. Van Der Lann had been gone much longer than half an hour. Vevi knew she would have to start home at once if she were to be on time for supper.
“I must go right away,” she said. “I will see you tomorrow, Hanny. Thanks a lot for the bag of bulbs.”
“Uncle Peter will take you home if you wait.”
“I had better go now,” Vevi decided. “My Mother will be expecting me.”
