Murder on the Orient Express
"Ratchett had escaped justice in America. There was no question as to his guilt.

"I would have stabbed that man twelve times willingly. It wasn't only that he was responsible for my daughter's death and her child's, and that of the other child who might have been alive and happy now. It was more than that. There had been other children before Daisy – there might be others in the future." (3.9.83)
