Assassin RP Interest Check

I have an idea for a psychological/horror/action/adventure role play involving some detective work and an assassin. (This is not a play off of Assassin's Creed for clarification)

Plot

A series of grisly murders is happening in a town/city (which will be decided later) where the victims are killed in ways that relate to one of the seven deadly sin which the victim supposed has committed: Lust, Gluttony, Greed, Sloth, Wrath, Envy, and Pride. Despite the rather gory crime scenes, little to no evidence of the murderer is found by police or the authorities.

When the assassin strikes again and fails to silence two targets, (me and one other player), those victims begin to delve into a world of psychological horror as they work against the clock to figure out who attacked them, to keep themselves and their families safe from the assassin, and to bring the assassin to justice before he strikes again. However, the odds are against the survivors as the assassin is shrouded in mystery. Some believe the assassin is only a rumor, some believe he is a criminal genius, and others do not know or care to know. However, one thing is for certain...how can someone who has no name or identity be stopped?

End Plot

So I hope this interests some people and I look forward to setting up this role play. Thank you for reading this.
