There's no walkthrough. I'm assuming you're referring to the Dairy Conspiracy quest given you mentioned Melanie ("bakery woman"). The hideout is located here:
I know that but how to get inside and place that thing the creeper asked to put in leader's cabin and what about the riddle given by talking latern light for Isabella quest?
The Old Man gave you a key, so just enter and go down the stairs. Light the two flames and the 'steel' door will open. Just go through the now opened doors after that. One flame is in the upper left by a level 4 door and the other is up at the top right. To get to that one: go all the way over at the bottom and then up. The thumbnails show the two flames lit and the door opened (don't have one before quest is done) and where you should go to get up to the right flame.
You should get it automatically from the Panty Smuggler/Old Man when you talk to him during the Dairy Conspiracy quest. The lettering on the the building will only turn from white to green once that happens and thus, allowing you to enter.
After the quest completed for Melanie, the old man gives a side quest after that quest is completed he gives a key as reward. Where can I find the lock for the key? What's with the key?
I think that key is to that side room in the bakery basement with all that fire stuff. At the top right of the market district the bakery is there and just go back down to the basement and go to the door you couldn't access before. (this is just memory lol, I went to double check and make sure but I think I accidentally deleted the game when I cleaned up my downloads so I might be wrong)
Yes. You just need to take advantage of and use the Cloak of Invisibility, which Isabella bestowed upon you. It does require a little patience and timing, but apart from that...the 5 seconds you have to get around and then find a hiding spot while you wait the allotted 15 seconds before you can use it again is ample.
Can you tell me how to use cloak? When i trying to use it from inventory it making "wrong" sound.
Yes, it's just an item letting you know you have the ability. Press T on your keyboard to use the ability. Clock/timer starts immediately, so make haste. As always with RPG, save as you go.
