Interesting theory that the novelist was either murdered with arsenic or, more likely, poisoned accidentally. Arsenic was prescribed for various ailments at the time.
It's a debilitating poison that does not kill that quickly. I remember meeting someone whose spouse tried to kill him that way, but his doctor figured it out in time. Unfortunately, it ruined his health, anyway. Amazing that it was once prescribed as a medicine.
"Immersion in the life of the world, a willingness to be inhabited by and to speak for others, including those beyond the realm of the human, these are the practices not just of the bodhisattva but of the writer." --Jane Hirshfield
