- there is a well in the middle of the basement. Somebody once fell in and died. People say if someone throws food into the well they will be given a reward.
- the man fell into the well on september 2nd 1952. One week later he died. So the date of death is the 9th of september 1952.
- there also are two pages with hints to several codes. Close the diary. Click navigation-bar to go right.
