You have been found guilty of a crime that you haven’t committed. Sat in your prison cell with your co-accused you have nothing to do but contemplate the next twenty years behind bars, whilst the real criminal walks free.
However, the four members of the jury all have troubles of their own. If you can help solve each of their problems they have promised to find you innocent at your trial and you will be able to walk free.
The clues to their problems are all in the Sheriff’s office somewhere. If you manage to get out of your cell you will be able to find the information needed.
You have an hour before the trial is due to start. Manage to work out the puzzles and you walk free. Fail and it’s the hangman’s noose for you.
