This question already has an answer here:
I know somebody asked what happened between Jack Crusher and Picard. I also read the answer which I already knew. There was an accident on the Stargazer, Picard had to choose between life or death, Picard is somehow responsible for making a choice that led to Jack Crusher's death. These sets of facts were laid out over many episodes.
Do we know the actual reason how and why Beverly Crusher's husband died? What was the away mission? What were the circumstances? What decision did Picard make?
Is there anything in the novels or anywhere else that describes the details of the away mission any more than what I've stated already?
