Would this TV series interest you?

Thinking of a concept for a dramatic TV series, an idea came where we are introduce to at least three new characters with their own separate or intermingling stories in each episode.

At the end of each episode, always one of them dies. Always.

The only constant character is a mysterious figure which observes and follows the other characters. Appearing as either human or an animal or sometimes just a mere “presence” from the POV of the other characters.

It is not clear whether this character is Death, an angel or something else different entirely.
