The Mysterious Letter

(You do not need to listen to this specific audio at the given location). Sitting in your home on a nice quiet evening you hear the doorbell ring. You wonder who it could be considering it’s late and you weren’t expecting anyone. You check through the peephole to see if anyone is outside but weirdly enough there isn’t. You open up the door just to double check. There is no one. Frustrated with this minor inconvenience, you just about slam the door until you notice a brown paper bag laying on your doorstep. You pick it up to inspect it until you notice a dark shadowy figure running towards an unmarked car. You shout asking "who is there?" but they do not respond. Feeling unsettled and confused you closed the door and sat down to investigate what was inside.

Inside the bag are 5 tapes and a tape recorder all marked in numerical order, including a note that is addressed to you. Click the sound to hear what is written in the letter.
