I just listened to a short story by George Eliot wherein a dead body was revived via a blood transfusion long enough to accuse a character of attempted murder.

Cats sucking the breath out of babies.

I’m trying to think of the 400,000 after you’ve counted Korea and Vietnam.

I think he meant the Nazis.
