"That was a pretty important case, Chief," Elmer replied, "and I didn't want to take any chances of the findings being lost in the registered mail." Then, grinning, he continued, "Understand you've been having a bit of trouble out in Columbus?"

"Who told you about that?" growled the chief.

"Oh, you can't keep things like that under your hat even if you do succeed in keeping them out of the papers," retorted Allison. "A little bird tipped me off to it three weeks ago and—"

"And you determined to leap back here as soon as you could so that you would be assigned to the case, eh?"

"You guessed it, Chief. I wanted a try at the Columbus affair and I was afraid I wouldn't get it unless I put the matter personally up to you. How 'bout it?"

"As it happens, you lost about two days of valuable time in coming here, instead of wiring for further instructions from Kansas City," the chief told him. "I had intended taking you off that anonymous letter case by noon to-morrow, whether you'd finished it or not, for this is a far more important detail. Somebody's gotten away with fifty thousand dollars so far, and there's no—"

"Pardon me, sir, but here's a wire which has just arrived from Rogers, in Columbus. Thought you'd like to see it at once," and the chief's secretary laid a yellow slip face upward on his desk. Allison, who was watching closely, saw a demonstration of the reason why official Washington maintained that the chief of the Postal Inspection Service had the best "poker face" in the capital. Not a muscle in his countenance changed as he read the telegram and then glanced up at Allison, continuing his sentence precisely where he had been interrupted:

"Reason to suppose that the thief is going to stop there. This wire from Rogers, the postmaster at Columbus, announces the loss of a fourth package of bills. Fifty thousand this time. That's the biggest yet and it brings the total deficit up to one hundred thousand dollars. Rogers says that the banks are demanding instant action and threatening to take the case to headquarters, which means that it'll spread all over the papers. Congress will start an investigation, some of us will lose our official heads, and, in the mix-up, the man who's responsible for the losses will probably make a clean getaway."

Then, with a glance at the clock which faced his desk, "There's a train for Columbus in twenty minutes, Allison. Can you make it?"

"It's less than ten minutes to the station," replied the operative. "That gives me plenty of leeway."
