Magnificent Obsession

Lloyd C. Douglas's 1929 novel 'Magnificent Obsession' is about Robert Merrick, who is resuscitated by a rescue crew after a boating accident. The crew is thus unable to save the life of Dr. Hudson, a physician renowned for his ability to help people, who was having a heart attack at the same time on the other side of the lake. Merrick then decides to devote his life to making up for the doctor's, and becomes a physician himself.
