“Operatives of our service, after months of patient and very skilful work, have run down what we believe to be the greatest criminal organization of its kind the country ever saw. It is almost a certainty that every mail robbery of any size since 1919 has been engineered and carried to a successful completion by this organization.

“The group is so powerful and so wise that its ramifications are almost unbelievable. We don’t know all about them yet, but we do know that its organization includes agents all over the country for the safe disposal of securities and other valuables; that it includes brokers, business men, cracksmen, gunmen, government employees. The brains of the gang, the man to whom all credit for the conception and execution of these tremendous crimes and the organization of the whole thing goes is Stanislaus Hayden.

“I won’t bore you with his history—suffice it to say that he is one of the most remarkable combinations of brilliancy, far-sightedness, and executive ability that I have ever known about. If he were anything but a mentally and morally warped specimen, he might have been another Morgan or Stinnes.

“Now here is the situation. Hayden is at present in West Virginia. He is living on the top of a mountain in Farran County, miles from the nearest town. With him are several underlings—I believe them to be some of the men who actually pull the robberies themselves. Just why they are living in seclusion up there I do not exactly know, but I presume that it is first of all a good hiding place, and secondly that it keeps Hayden away from the surveillance of the police. He has been mixed up in some monumental deals—or at least suspected so strongly that he is watched—but for two years he has fooled us completely on this new organization of his. What makes him unusually dangerous aside from his ability is the loyalty he inspires in those under him—rather a combination of loyalty and fear, I should say. Anyway, a few small potatoes whom we have nabbed quietly will tell nothing. Apparently they realize that he is a really great commander-in-chief, and trust him to help them.”

“But how did he⸺”

“How he got into West Virginia I do not know. A year ago he dropped from sight, and the operative who finally traced him down has no idea when he came into that part of the country. I believe that the gang planned to quit operations before long, and that for months Hayden has been a hermit simply making his pile with the idea of retiring on his money in the near future. He would not be safe in any city in the country to carry on his operations.”

Graves talked as precisely as ever. Every word was clear-cut and incisive. His slim, long-fingered hands were motionless except as he carried his cigar to his lips. He paused a moment to get up and drop the stub into the ash receiver.

“As I said, Hayden is staying on the top of a mountain in Farran County with some henchmen. There is no question that all of them would fight to the death—you know what the Postmaster General announced recently about mail-robbers, do you not?”

“It was plenty,” nodded O’Malley.

“There are several facets to the situation. In the first place, that little nucleus of men is well supplied with artillery and ammunition ranging from machine-guns down. In the second place, their dwelling place is so strategically advantageous that it might take a hundred men dead and wounded before they could be captured. The only road leading to the hunting cabin where Hayden has his headquarters is narrow and winding, like all those mountain roads, and by reason of a three or four hundred foot precipice and some other details of the country a dozen men could hold the place for a considerable time against ten times their number.
