umm if u go over to the trash can and if u dig in there ull find the tickets but then u have to take them to the guy at the cafe and then he gives u one ticket:)
the detective is at the end at of the underground tunnel.
you have to go in the trash
go to the tunnel
you enter the tunnel by getting the ticket which the tickets are at the ticket place
you go to main street and there is a garbage can with no lid on it then at the very bottom of the garbage can then you go to the news place and then you get a ticket from him
You need to go down in the tunnel, and go meet this guy, then he will tell you what to do from there.
You go and show it to the dude that ask you to find the ticket and then he will take it from you, then he will give you one. After you got a ticket go the person that's next to the tunnel and show it to her.
The landmark is right above the tunnel past the four big containers and before the ticket office. If u go through the tunnel traveling towards the ticket office it will be to ur right, but u have to go up the hills first.
He is at the end of the old tunnel , but he wont be there until you get the ticket and give it to the lady .Then you have to go through the tunnel , when you get to the end of the tunnel, the lady will say that it is the end of the tour and she will leave will step outside and he will be there.
You get tickets from the second garbage can by tunnel and take them to man in the coffee cafe and he'll give you one.Then you go up a lightpole and you see the ticket.
You give the ticket to the tour guide and then she lets you into the tunnel.
