Before you will do that look at some things in the shop. Remove piece of hook for snake that is located on the regale board on the right. Go near the door and take a cage with a tight mesh.
Now you have to go to the shoemaker (use map). Ask him if you can borrow tongs. Take metal shrank and iron thread too.
Now return to the pet shop. Use metal thread and tongs to connect hook with the shank to form a snake pole. Go to the large cage with the snake (right of the door). Put a smaller cage in front of it and take it out (click on the large snake with activated pole). Now you can take your tanner's mask.
Go into Finley Bed & Breakfast (use map) and go to the abandoned building. Put on your mask (click it in inventory). Walk to the gas installation and click on the hidden bag (zoom).
You can see a board, where you have to restore missing pipe and switch some gas knobs.
Now you have to connect the pipes and weld them. It is necessary to bring gas from a main pipe (the thicker) to the lower pipe (on the left). You will find a manometer there so put it to hole with number 3. However manometer that was put there shows zero. You must close and open (with three knobs) a gas stream in other pipes. The pressure gauge in hole No 3 must show 100.
So go for it. The upper knob (at hole No. 1) shows 50 - to turn to the left (PPM) to decrease it to zero. Move pressure gauge to the hole No. 2 (shows zero) and turn the middle wheel to the right (LPM) - it will rise the gas pressure to 50. Now you have to close down the gas stream in the main pipe. Move the manometer to the hole No. 4 (it will show 50) and turn the lower knob to left (PPM. Now it will show zero. Make sure that the pressure gauge at the hole No 3 shows 100 - if so, you can start working.
Point the flame to each of the five connections. When you will do it in the right way you will see sparks. When the work will be done (installation will change color to dark red) click left mouse button.
Now you have to supply the main pipe with the gas to finally repair the installation. To do this, turn off the middle wheel (near the hole No. 2), so that the pressure gauge will show zero. Take manometer to the hole No. 1 and open the gas (LPM) by turning the upper wheel - pressure gauge should show 50.
Of course, pull out the Bluto's Bag from the pipes. Holmes will not honor the promise given to Bluto and he will check the bag. You find some stolen jewels there. Replace them with some rusty pots. When you will be going down, take the kitten, remove the mask and go to the pub.
Give the bag to Bluto (click it in inventory and then click on the door). Talk to him about Squibby. You will learn that sitting in custody. When you will give the bag to Bluto it will be good to just go away very quickly. Holmes will now go to the zoo shop (use map). It is time to resolve the issue of the cat. In front of the shop Holmes will find his informers. You will learn that one of them has lost the cat scared by Big Danny. Of course, this is the kitten found by Sherlock. After finishing the conversation, go to the shop. Bertie and Pounce will go with you.
Bertie is injured, so ask Abraham for help. The Jew will ask Holmes to bring the Spartaca Encyclopedia, where Holmes will read that cats like the smell valerian. Leave the kitten in the care of Solomonovitch and go to the police station (use map).
When you will click on the door Holmes will find that he must be sure whether Squibby is actually inside and then scare of the policemen. Go to Commercial Street, where you will find Big Danny. Woman does not want to give Holmes any information. Go to the brothel (use map). Ask Lucy whether police officers are the customers of this place, and the ask Bella about some bottles. You will find that these are the Paris perfumes, which was left by one client in the form of the payment, but the woman does not know which of these are actually real perfumes and she fears that they ma badly affect girl's skin. Sherlock will decide to examine the content of the bottles. As a payment he will receive some information about Squibby. Take the case of perfumes.
