“Did Mr. Howard get any news of the robbers?”

“We haven’t heard anything from him this morning, but your father plans to stop at his office on the way in to town.”

While Roberta was eating her belated breakfast any number of neighbors came in to congratulate the family because its property was safe, and, those who did not know the facts, to get details of the attempted theft. Once the conversation was interrupted by the sudden and sharp clanging of a bell which made them all jump. But Mrs. Langwell glanced out of the window and saw the electrician waving his hand so she knew he was merely testing the alarm, and reassured the callers.

“Sounds louder than the fire bell,” Roberta remarked, and they agreed that she was right and it would certainly wake everybody in the neighborhood if it went off at night.

After the guests had taken their departure the girl helped her mother and when the bell was finally installed, they went out to inspect the job. The alarm was set low on the wall, the wiring ran back through the thick planks, which had been bored so they were not exposed, and could not be either ripped out or cut without difficulty.

“Keep them set all of the time,” the man explained, “and remember whenever you want to open the door to switch them off. I’m to put some more on the windows, so your plane will certainly be well protected and ought to be safe.”

“That’s what we want,” Mrs. Langwell told him, then turned to her daughter. “That is our telephone, dear.”

“I’ll go and answer it,” Roberta replied, and ran to the house as fast as she could. The bell was still ringing so she knew that the party had not been discouraged over the delay and given up getting in touch with the family. “Hello,” she spoke into the phone.

“I wish to speak with Miss Langwell,” came the reply, and although the voice sounded familiar, Roberta could not recognize it immediately.

“This is Miss Langwell,” she said.
