In a sense, I think every writer of thrillers touches on the theme of "buried alive", just because the sense of horror it creates is more convincing.When I was about seven years old, the scariest TV show on was Alfred Hitchcock.The scariest of these—my friends and I agreed—was a character in the show named Joseph Court who was injured in a car accident.His injuries were so severe that the doctors thought he was dead because his heart had stopped beating.They're about to do an autopsy on him -- in other words, cut him up while he's still alive and screaming from the bottom of his heart.Suddenly, he shed a tear, letting the doctors know he was not dead.It's a really touching story.But the word "moved" doesn't appear often in my "life" repertoire.When my mind turned to this topic, I suddenly thought of a more modern - can we call it modern? — and a new, dynamic way of communicating.So I wrote this story.A final word about this snake: I very much doubt that there is a reptile called the "Peruvian African Tree Snake".But in Damon Agatha Christie's absurd series "Miss Mapp", there is indeed a mention of an African tree snake.I like that word so much ("tree snake" instead of "African") that I included it in this story.
