Fortunately the chief of police, Mr. Durand, was in, and he greeted Mr. Brandon with a heartiness that showed they were old friends.

After they had shaken hands, Brandon introduced the radio boys, and then proceeded to acquaint the chief with the details of the plot they had discovered. As Mr. Durand listened a dark frown gathered between his bushy eyebrows, and his fingers drummed angrily on the table before him. When Mr. Brandon had finished, the chief jumped to his feet and strode fiercely up and down the room.

“This won’t be the first trouble we’ve had with those rascals!” he exclaimed wrathfully. “Members of the same gang have held up and robbed stores in this town, and we have two of them doing their bit in jail right now. And if we have any luck to-night we’ll have the whole gang under lock and key before the morning. These young fellows must have been right on the job from start to finish, Frank.”

“Yes, I guess they were,” replied Brandon. “If we land this gang, we’ll have them to thank for it. But now what are your plans for capturing the crooks?”

For answer the chief pressed a button, and a capable looking police lieutenant appeared.

“Get together ten of our best men,” he directed, “and put them into two automobiles. When they are ready to start, report to me.”

The lieutenant saluted, and left the room.

“According to the code message, the robbers won’t be at Hicks Bridge much before eight o’clock, which is after dark these days,” said the chief. “We’ll get there a lot earlier than that, and I’ll conceal my men in the woods. Then I’ll leave orders here to stop the motor truck as it comes through, and replace its crew with a few picked men from my force. When the robbers try to hold up that truck, they’ll have a big surprise in store for them.”

“It might be a good plan,” suggested Bob, “to mount a searchlight or two on the motor truck. At the right minute you could turn these on the crooks, and while it would confuse them, it would give your men in the woods a big advantage, as they’d be able to see the hold-up men plainly without being seen themselves.”

“Young man, that’s a first-rate suggestion!” exclaimed the chief, eyeing him appraisingly, “and you can believe we’ll take advantage of it. I’ll commandeer a couple from the Electric Light Company in readiness to mount on the truck when it comes along. I wish we could persuade you and your friends to join the Barberton police force.”
