Bell lurched at Sullivan. He was gasping at the exertion, but his face was a mask of grim purpose: Who hiredjou to kill me?

Sullivan dropped to his knees beside Corbett, reached inside his fallen partner's coat, yanked out a flick knife. Leaping to his feet, he charged Bell.

Bell knew that the heavily built brawler was stronger than he was. In his own half-dead state, attempting to take the knife away was too risky. He slipped his own blade from his boot and pitched it overhand, dragging his index finger on the smooth handle to prevent it from rotating. Flickering like a lizard's tongue, it flew flat and true into Sullivan's throat. The brawler fell, spewing blood through hands desperately trying to close the wound.

He would not be answering Bell's questions.

The detective knelt beside Corbett. His eyes were staring wide open. Blood was trickling from his mouth. If he wasn't dying from internal ruptures from Bell's blow to his stomach, he was close to it, and would not be answering questions tonight either. Without wasting another moment, Isaac Bell staggered along the rails to the Rawlins Depot and burst through the dispatcher's door.

The dispatcher stared at the man in ripped evening clothes with blood pouring down his face.

"What the hell happened to you, mister?"

Bell said, "The president of the line has authorized me to charter a special."

"You bet. And the Pope just gave me a pass for the Pearly Gates."

Bell pulled Osgood Hennessy's letter from his wallet and thrust it in the dispatcher's face.

"I want your fastest locomotive."

The dispatcher read it twice, stood up, and said, "Yes, sir! But I've only got one engine, and she's scheduled to hitch onto the westbound limited, which is due in twenty minutes."

"Turn her around, we're going east."

"Where to?"

"After the Overland Limited."

"You'll never catch her."

"If I don't, you'll be hearing from Mr. Hennessy. Get on that telegraph and clear the tracks."

The Overland Limited had a fifty-minute head start, but Bell's locomotive had the advantage of hauling only the weight of her own coal and water while the Limited's engine was towing eight Pullmans and baggage, dining, and observation cars. Hundred-dollar tips to the fireman and engineer didn't hurt her speed either. They climbed through the night, encountering snow in the Medicine Bow Mountains, a harbinger of the winter that Osgood Hennessy's railroad builders were striving to beat even as the Wrecker sowed death and destruction to stop them.

They left the snow behind as they descended into the Laramie Valley, stormed through it and the town, stopping only for water, and climbed again. They finally caught up with the Overland Limited east of Laramie at Buford Station, where the rising sun was illuminating the pink granite on the crest of Sherman Hill. The Limited was sidetracked on the water siding, her fireman wrestling the spigot down from the tall wooden tank and jerking the chain that caused the water to flow into the locomotive's tender.
