"He did not!" exclaimed Gregson, half delighted and half appalled.
"Oh, he did," Bradstreet assured him. "From broken neck and asphixiation to losing one's bowels."
There was a pause.
"Didn't think the doctor had such a malicious streak in him," MacDonald mused aloud.
Bradstreet shrugged. "I don't think he would have done it, if that blighter hadn't shown such a disregard for human life. Tit for tat, as it were." He chuckled slightly. "You should've that fellow's face when Watson finished."
There were schuedenfreude-esque chuckles all around as they imagined the "punisher" -- responsible for three deaths by beating and countless other attacks -- contemplating the manner of his own death. He had taken pride in his "work"; he faced his own death with less aplomb.
Bradstreet joined in, though he kept one detail private. Watson had found a savage satisfaction in relating the information and yet there had been pity too. He knew how it felt to be trapped by circumstances and could find a little sympathy even for the villain who attacked him. And that, Bradstreet reflected, was the line that forever separated good men from brutes.
