“Well, you had best give me a night or two that I may see the house and make my plans. Then—”

“Very good,” said McGinty, shaking him by the hand. “I leave it with you. It will be a great day when you bring us the news. It’s just the last stroke that will bring them all to their knees.”

McMurdo thought long and deeply over the commission which had been so suddenly placed in his hands. The isolated house in which Chester Wilcox lived was about five miles off in an adjacent valley. That very night he started off all alone to prepare for the attempt. It was daylight before he returned from his reconnaissance. Next day he interviewed his two subordinates, Manders and Reilly, reckless youngsters who were as elated as if it were a deer-hunt.

Two nights later they met outside the town, all three armed, and one of them carrying a sack stuffed with the powder which was used in the quarries. It was two in the morning before they came to the lonely house. The night was a windy one, with broken clouds drifting swiftly across the face of a three-quarter moon. They had been warned to be on their guard against bloodhounds; so they moved forward cautiously, with their pistols cocked in their hands. But there was no sound save the howling of the wind, and no movement but the swaying branches above them.

McMurdo listened at the door of the lonely house; but all was still within. Then he leaned the powder bag against it, ripped a hole in it with his knife, and attached the fuse. When it was well alight he and his two companions took to their heels, and were some distance off, safe and snug in a sheltering ditch, before the shattering roar of the explosion, with the low, deep rumble of the collapsing building, told them that their work was done. No cleaner job had ever been carried out in the bloodstained annals of the society.

But alas that work so well organized and boldly carried out should all have gone for nothing! Warned by the fate of the various victims, and knowing that he was marked down for destruction, Chester Wilcox had moved himself and his family only the day before to some safer and less known quarters, where a guard of police should watch over them. It was an empty house which had been torn down by the gunpowder, and the grim old colour sergeant of the war was still teaching discipline to the miners of Iron Dike.

“Leave him to me,” said McMurdo. “He’s my man, and I’ll get him sure if I have to wait a year for him.”

A vote of thanks and confidence was passed in full lodge, and so for the time the matter ended. When a few weeks later it was reported in the papers that Wilcox had been shot at from an ambuscade, it was an open secret that McMurdo was still at work upon his unfinished job.
