“What for?” asked Jerry. “Especially after the money is gone—fifty thousand dollars of it?”

“Sixty thousand would be nearer the figure,” declared Mr. Thompson. “It does seem sort of like locking the stable door after the horse is stolen, but orders from the chief are orders. Besides, it takes quite a few of us to keep the crowd back, and the rest are looking for clews.”

“Inside the bank?” Ned wanted to know.

“Inside and outside. The robbers made a neat job of it, and the funny part of it is that we can’t seem to find out how they got in and got out again. However they got the money all right—a clean sixty thousand. But what are you boys doing here?”

“We took part in the airship meet at Colton,” said Jerry; and they told Officer Thompson about it, of how they had seen the crowd, and stopped off the car to learn the cause of the excitement.

“I wanted to get a picture of the wrecked safe,” put in Bob, “but I——”

“Say now, I’m glad I met you,” interrupted Mr. Thompson. “It’s a little against orders, but I guess I can let you in, especially as no one is looking. Slip around in back of me, and go to the rear door. Wait there for me, and as soon as I can get some one to take my place I’ll bring you in, and show you the way they did it. It’s worth seeing.”

They had not been waiting at the rear door of the bank more than a few minutes, and had seen, through the windows, a number of men hurrying here and there, when their friend came up.

“It’s all right,” said Mr. Thompson. “Come on, I’ll take you in.”
