The old mansion stood silent under the dark stormy sky. Inside the grand hall a lifeless body lay perfectly still. Deep red blood stained the expensive carpet underneath his body. Detective Harlan arrived promptly to investigate this strange mysterious case. He carefully examined every single clue left at the scene. Who among the guests could be the cold killer tonight?
