The Sentence.

Nathan’s ex-wife commits suicide while in prison. Months later, Nathan receives a text with only a period and someone he cares about dies. Soon he receives a single word with a period after it and another person he cares about dies. 

The sentence is revealed in reverse, one word at a time. All he has is a box of her oddities, a suicide note and superstitions to stop her spirit before the sentence is completed and everyone he cares about is dead. 

Could you solve the mystery of a demonic text-before everyone you know is dead?
