Now you can call a deduction board: choose it on bar on the bottom on the screen and click "Deduction - Knightsbridge".
When windows with Holmes' observations, click on "Lack", then "Shoes" and from the available options choose "One of the murderers left wearing the Bishop's shoes"
And later: The murderers are poor.
Click on "Wealth" and "Veranda" and then choose: The murderers were looking for something specific.
And next: The Bishop's murderers were hired by someone.
When you make a good conclusion, the windows become green.
Go on the second page, clicking the down arrow and click "Chest", "Torture" and "Penitence" and choose: The Bishop resisted torture.
And then: The Bishop's murderers didn't get what they wanted.
At this point Holmes asks a priest for opening the chest and when he refuses, detective agrees that clergyman with Watson should go for police.
