Dust

Shimmon Lehrer has given up on life. Loneliness, age and household chores have defeated him.
That's why he created Joseph.
Joseph is a golem. He looks human, but he's as strong as Hercules - and invulnerable. He's also missing a soul, so he can't speak, think or feel emotion. He has no concept of right and wrong.
Fortunately, a golem will only obey its master and, since Shimmon only wants help with the housework and groceries, what could possibly go wrong?
