Holmes will tell Watson to find a butcher and 12 fresh pig heads. Watson will start his mission in the brothel (use map).
Lucy will recommend Watson to meet a man named Fletcher (new location on the map - Fletcher's Butcher Shop). However you will find that it is closed - the owner is sick. Go down the street (left) and get to the clinic. Doctor Gibbons may know something about Fletcher. He will confirm that the butcher is sick and, as a matter of fact, he went to the village. The second person, who have the key to the slaughterhouse, is Hardiman, street kebab vendor. After leaving the clinic Watson will automatically speak with Big Danny. He will learn that Hardiman lives on the Hanbury Street (where the second murder was done, this is the location between Whitechapel and Baker Street).
You will immediately find Hardiman because of his strange voice. Talk to him and you will find that there is a problem with getting into the slaughterhouse: the man has broke and lost his key. You need to find it and fix it. Go to the shop located in the yard where Annie Chapman was murdered.
This time, go upstairs to the first floor. Go to the end of the corridor, where you will find a key. Get out to the courtyard. Open the door on the left, you will find a basic key there. Give it to Hardiman and talk to him about these pig heads.
As a result, Holmes and Watson are again in front of the slaughterhouse door. Click on the door to open it. You will find some pig heads there. To be able to do the experiment, Holmes must have access to the another room, which door are closed.
With the knife, remove upper left small wheel. Now move the hook to the door and connect it with the hinge. Then, again use your knife, to remove the damaged lower wheel and insert in this space previously removed wheel from the top.
When you will open the door Holmes will ask Watson to bring him two knives. One small, quite bigger than a pocket knife and another with 13 inches long blade. As a Watson go to the another room and find these knives
With your measure tape check all knifes and take the last one.
Take your magnifying glass and look at shorter blades. Take the first one.
Wrongly selected knifes can be changed. If you will bring Holmes the wrong knife, you will be informed about this.
When you will complete his order, talk to Sherlock and he will explain his friend what you will be doing now. With the aid of 4 knives (a short knife, pocket knife, scalpel, and the long knife) you have to hit each of the three pig heads (just smash the head with the mouse cursor to hear the Sherlock comment).
Holmes wants to see how each of these blades will behave in all type of cuts, which was performed by the assassin. Click on the table to start the task.
Experiment 1 (click this text). The first hit should cut the victim's throat. Do it with every knives, and Holmes will evaluate everything. Mark the first and the last blade.
Experiment 2. This strike have to cut off the victim's head. Do it with every knife and mark blades: 2, 3 and 4.
Experiment 3. This time the strike should be more delicate but also deadly. Do it with every knife and mark blades: 1, 3 and 4.
Now, on the basis of the experiments you have to choose a knife that would be able to perform each of these three strikes presented. This is, of course, a knife number 4. Drag it to the empty box at the bottom of the screen.
The next step is to visit the pub (use map). As a Sherlock go inside and talk about the third crime with barman and the journalist. As a Watson speak with the police officer, who has just appeared on the street. You will learn some facts about the murder.
