The story of the game takes place over six days between 24 and 29 December 1997, in New York.

On Day 4, at St. Francis Hospital, on your first visit to the room where you meet a nurse and patient (the room just after you enter), check behind the locker at the top of the room. You will find a sticker, but if you keep looking you will find an additional sticker each time. This trick only works once though.
