A night at the pub - questions

[Zaccheus]

I've got in and knocked out everyone in the pub and side room, and also in the bed room. I've searched everything, but now I'm stuck.
I've found a key, but can't find any secret entrance.

LOL! This is a tricky bit. Go outside and check the tree for a lockbox.

[Zaccheus]

Oh boy.
:o

I should have known that in Thief, "checked everything" must include everything.
LOL.

Thanks Nightwalker!
