Jessie noted that the tower stood on a knoll behind the house from which vantage the race track some quarter of a mile away might be seen. With good field glasses one might stand in the second story of the tower and see the horses running on the track. Then, if there was a sending radio set in the tower, the reports of races could be broadcasted in secret code to sets tuned to the one in the tower.
Of course, if the radio instrument was so illegally used, it was only so used while the races were being held at the Harrimay Track. Then the folding aerials were raised and made use of. The cry for help that had been broadcasted and which Jessie and Amy had heard might have been sent out from this station some night when Martha Poole or her friends had neglected to shut off the aerial by dropping it flat upon the roof of the tower.
The question now was, had Bertha stolen her way into the tower at that time, or was she held prisoner there? Evidently Martha Poole and Sadie Bothwell were determined to hold the girl until after the court had settled in their favor the Ellison will case.
Jessie and those with her came to the foot of the tower. All the lower windows were boarded up and the door was tightly closed. There were shades at the upper windows, and they fitted tightly.
“You call Bertha, honey,” said Jessie. “Tell her we’ve come to let her out. Did you try that door, Darry?”
“Not much! We don’t want to be arrested for trying to commit burglary.”
“Shout for Bertha, Henrietta,” commanded Jessie.
Immediately the little girl set up a yell that, as Burd declared, could have scarcely been equaled by a steam calliope.
“Bertha! Bertha Haney! Come out and see my new dress!”
That invitation certainly delighted Amy and Burd. They sat in the car and clung to each other while they laughed. Little Henrietta’s face got rosy red while she shouted, and she was very much in earnest.
