Cartwright fumbled for his own revolver, but Starbuck pointed the gun momentarily at the frightened face and Cartwright immediately subsided. Starbuck shifted the gun back to Dennison. “Second chance coming up, Captain, sir. Dear Emily, please lay yourself down and play mattress for me. Let’s see how lucky you are the second time of asking, Captain.” He pulled the trigger and once again Dennison shuddered as the dead click echoed loud in the room. Starbuck immediately spun the chamber a third time and straightened his arm.

“You’re mad, Potter,” Dennison said, suddenly seeming very sober.

“I’m sober too,” Starbuck said and reached out with his left hand for Cartwright’s brandy, which he drank in one go. “I’ll be madder still when I’m drunk,” he said, “so how many chances do you reckon you’ve got with my wife, Captain? Are you going to ask her three times for the favor of a ride?”

Dennison considered reaching for his own revolver, but it was buttoned in its holster and he knew he would have no chance to free the weapon before a bullet slashed through the candle flames and shattered his skull. He licked his lips. “I guess I don’t have any chance, Lieutenant,” he said.

“I guess you don’t, Captain,” Starbuck said, “and I guess you owe me an apology too.”

Dennison grimaced at the thought. “You can go to hell, Potter,” he said defiantly.

Starbuck pulled the trigger, then immediately half cocked the gun and spun the cylinder a fourth time. When it came to rest he pulled the cock back and this time he could see the single percussion cap was waiting under the hammer. He smiled. “Three times lucky, Captain, but how good is your luck? I’m waiting for that apology.”

“I apologize, Lieutenant Potter,” Dennison managed to say.

Starbuck eased the hammer down, thrust the Adams into its holster, and stood up. “Never start what you can’t finish, Captain,” he said, then leaned forward and picked up the half full bottle of brandy. “Reckon I can finish this, though, but in privacy. You all have a nice conversation now.” He walked out of the room.

It was a humid, rainy night in Washington with no wind to take away the thick stench of the garbage dump that lay at the southern end of Seventeenth Street just a few yards from the hospital tents pitched on the ellipse. The sewage in Murder Bay added its own fetid smell to the air above the Northern capital that was more than usually crowded with soldiers. They were men who should have been marching in John Pope’s army toward Richmond, but instead they had been whipped backward by Robert Lee from the banks of the Bull Run and now they filled the tented camps inside Washington’s ring of forts and thronged the capital’s taverns.

One young cavalry officer hurried along Pennsylvania Avenue to the corner of Seventeenth Street, where he took off his wide-brimmed cavalryman’s hat to peer up at the street lamp. At every corner in Washington the lamps had their street’s name painted in black on the glass covering the mantel, an intelligent device, and once the young man was sure he was in the right place he walked up Seventeenth until he reached a three-story brick building that was thickly surrounded by trees. Gas lights showed where the building’s narrow end abutted onto the sidewalk and where a flight of steps led to a door guarded by two blue-coated sentries, though when the young cavalryman presented himself at that door he was told to go back to the garden entrance on Pennsylvania Avenue. He retraced his steps and discovered a driveway that led through night-blackened trees to an imposing portico of six massive columns that protected and dwarfed a small doorway guarded by a quartet of blue-coated infantrymen. Gas lamps hissed yellow under the portico, lighting a carriage that waited for its owner.
