As Holmes suggests, look at a deduction board and point the place where the journalist shouldn't be.

So click on a dropped book. Journalist's actions doesn't explain his approaching the bookshelf.

Move to bookshelf and click it. Holmes will remove remaining books and notice a control box behind them. Look at it.

A ciphered board appears. Notice, that below a hint is inscribed: +6. And dependences between symbols are with every second window (4 + 6 = 10). According to this, set:

• J (6th letter after D);
• 16 (10 + 6 = 16);
• P (6 letter after J).

And pull the lever.

Look into a hidden passage. You will find a hit, which a mysterious guest lost.
