However, I survived and started to read all chemistry books that I could get a hand on, first some 19th century books from our home library that did not provide much reliable information, and then I emptied the rather extensive city library.
The word survivor suggests someone who has emerged alive from a plane crash or a natural disaster. But the word can also refer to the loved ones of murder victims, and this was the sense in which it was used at a four-day conference in early June at Boston College.
Murderers will try to recall the sequence of events, they will remember exactly what they did just before and just after. But they can never remember the actual moment of killing. This is why they will always leave a clue.
