Mrs. Baggert was the first to greet Tom as they arrived at his home. She did not seem as surprised as either Tom, Ned or Mr. Damon expected her to be.
"Well, I'm glad you're all right," she said. "And it's a good thing you sent that note, for your father was so excited and worried I was getting apprehensive about him."
"What note?" asked Tom, while a queer look came into his face.
"Why, the one you sent saying you were detained on business and would probably not be home for a week, and to have Koku and the men bring the tank to you."
"Bring the tank! A note from me!" exclaimed Tom. "The plotters again! And they've got the tank!"
He ran to the big shop followed by the others. Throwing open the doors, they went inside. A glance sufficed to disclose the worst.
The place where the great tank had stood was empty.
"Gone!" gasped Tom.
