Off he went, for all the world as if he had a job to which he didn't want to be late. His landlady thought he did have a regular job. He'd made certain she thought that. If she thought anything different, the Yanks were liable to hear about it. That was the last thing he wanted.

Almost three years after the end of the Great War, Winnipeg presented an odd mixture of rubble and shiny new buildings, as if a phoenix had risen halfway from the ashes. In another few years, McGregor thought, it might turn into a handsome city again. The rubble would be forgotten. So would the buildings and the hopes from which that rubble had been made. The new Winnipeg would be an American city, not a Canadian one.

HORNE'S HOUSE PAINTS, said a sign on Donald Street. 37 COLORS AVAILABLE. If Horne had been in business before 1914, if he wasn't a johnny-come-lately Yank, his sign would have advertised 37 COLOURS then. Even spelling changed under U.S. rule.

McGregor scowled. To him, COLORS looked clipped, unnatural… American. He stepped off the curb-and almost got clipped himself, by an American motorcar. An angry blast from the Ford's horn sent him leaping back onto the sidewalk. "Watch out, you goddamn hayseed!" the driver screamed, in an accent unmistakably from the USA. "Ain't you never seen an automobile before?" He stepped on the gas and whizzed away before McGregor could say a single word.

"Christ!" McGregor wiped his forehead on his sleeve. "That'd be all I need, stepping out in front of one of those damn things when I'm carrying…" He let his voice trail away. He did not intend to mention out loud what he might be carrying. He wouldn't have come so close had he not just come close to getting killed.

Had so many motorcars scurried through the streets of Winnipeg before the Great War? McGregor had come up to the city only a couple of times in those days, so he couldn't be sure, but he didn't think so. It might end up prosperous as well as handsome.

He didn't care. He would sooner have been poor under King George than rich under the Stars and Stripes. The Yanks had taken his country away from him. If they expected him to be happy about it, they were in for a disappointment.

As a matter of fact, if they expected him to be happy about it, they were in for a big disappointment. He chuckled grimly-so grimly that a fellow in a business suit edged away from him. He didn't notice. He wanted to make sure their disappointment was as big as possible.

He crossed the Donald Street bridge over the Assiniboine and strolled past a three-story building that had somehow come through the war intact. Soldiers in green-gray with pot-shaped helmets stood guard around the building in sandbagged machine-gun nests that gave it a formidable defensive perimeter. He didn't linger. The U.S. guards asked pointed-or sometimes blunt- questions of people naive enough to linger around General Custer's headquarters.

They would, without a doubt, ask even more pointed-or perhaps blunt-questions of anyone foolhardy enough to try to leave a wooden box anywhere in the neighborhood. McGregor had seen as much on his last trip to Winnipeg.

There was a park not far away. It didn't even boast children's swings. All it had were grass and a few benches. McGregor sat down on the grass and waited for noon. He'd done that a good many times by now, and come to know the park well. The earth here was not smooth, but full of round depressions of different sizes and depths. A narrow zigzag strip of low ground, partly obliterated by the depressions, ran across the park from east to west. The troops defending Winnipeg had made a stand here. McGregor grunted. They'd failed, damn them.

He wasn't the only one out on this fine, mild day. Boys and girls frolicked where shells had burst and men had bled. An unshaven man in a filthy Canadian Army greatcoat and tattered khaki trousers lifted a bottle to his lips. He set it down slowly and reluctantly, as if its opening were the mouth of his beloved. In a drunken way, that was bound to be so.

McGregor killed time till the bells of the St. Boniface Cathedral, across the Red River, chimed twelve. He got up and ambled back by Custer's headquarters. He'd timed it perfectly. He'd just gone past the building when a chauffeur-driven Packard-the motorcar that had almost run him down in Rosenfeld when Custer was on his way up to Winnipeg-pulled away from the front of the place. He kept on walking, hardly looking at the automobile, and turned west, away from the Red River.

After a little while, he went up Kennedy. Sure as the devil, there in front of a chophouse called Hy's sat the Packard. The chauffeur remained on the front seat, eating a sandwich. General Custer and his aide, a tubby officer who seemed to accompany him everywhere, had gone inside.

McGregor smiled to himself. Custer dined at Hy's every Monday, Wednesday, and Friday. He was reliable as clockwork. He ate his dinner somewhere else-McGregor hadn't been able to find out where-on Tuesdays and Thursdays. So far as McGregor could tell, no swarm of guards surrounded him here.

Luck had had very little to do with McGregor's discovering his weekday routine, or at least three-fifths of it. The embittered farmer had taken to tramping the streets of Winnipeg during the dinner hour, looking for that Packard. Patience paid, as patience has a way of doing. McGregor walked past the motorcar on the other side of the street. The driver paid him no attention whatever. Had he suddenly turned around and gone back the way he'd come, that might have drawn the fellow's notice to him.

He couldn't have that, not when he was so close. He made his way back to the park, though he didn't go past Custer's headquarters this time. "Now they shouldn't see me at all," he said as he sat down on the grass once more. No one heard him. The children were gone. The ex-soldier had passed out. His bottle lay empty beside him.

A little past five, McGregor returned to the boardinghouse. He ate the landlady's frugal supper without complaint. Afterwards, he went up to his room and read Quentin Durward till he grew sleepy. Then he turned off the electric lamp and, so far as he knew, didn't stir till morning.

Since the next day was Thursday, Custer wouldn't be dining at Hy's. McGregor walked in, went over to the bar, and ordered himself a Moosehead. As he drank the beer, he studied the place. He couldn't very well plant the bomb among the seats; he had nowhere to conceal it there. But a lot of tables were close to the bar, and he'd packed a lot of dynamite and a lot of tenpenny nails for shrapnel into the wooden case he'd brought up from the farm. If he could hide it under the bar somewhere, that stood a good chance of doing the trick. The blast might even bring down the whole building… if the detonation worked as it should.

He worried about that, too. He'd known from his earlier trip to Winnipeg that he'd have to set this bomb and leave it. To make it go off when he wanted it to, he'd brought up an alarm clock, which he would set while he was planting the bomb. When it rang, the vibrating hammer and bells would set off the blasting caps he'd pack around them, which would in turn set off the dynamite. So he hoped, at any rate. But he knew the method was less reliable than a tripwire or a fuse.

"It will work," he whispered fiercely. "It has to work."

He got out of bed at two the next morning and sneaked out of the boardinghouse. He carried the bomb on his back with straps, as if it were a soldier's pack. In one pocket of his coat were caps, in the other a small electric torch and a pry bar.

Winnipeg remained under curfew. If a patrolling U.S. soldier spotted him, he was liable to be shot then and there. If he got shot, he was liable to go straight to the moon then and there, in fragments of various sizes. He was taking any number of mad chances with this venture, and knew it. He didn't care, not any more. Like a soldier about to go over the top, he was irrevocably committed.
