"Mr. McCarthy had me inquire."

"How do you account for it?"

"I don't know, except that maybe my instrument happened to be just tuned to catch it. That's another reason I know it was from far off. The farther away the sending instrument, the nearer exactly it has to be tuned to the receiving instrument. If it was nearer, 'most anybody'd get it."

Percy Darrow nodded.

"That's all, I guess. No, hold on. Did any of these come between six and eight last evening?"

For the first time the operator smiled.

"No, sir; my instrument was dead."

He went out.

"Well?" growled McCarthy.

"I don't know; but I can see more trouble."
