“I first contemplated murder in Pittsburgh. I was ten hours into a liver transplant on a guy from Durango, Colorado, when I wondered if I should remove the clamp and let him bleed out. It would be over in less than a minute and we could all go get breakfast and complain about burnt bacon. Worse things could happen to Mr. Durango. I could just tell his wife we’d done our best, and she’d probably thank me for it.”
