I just clearned the Temple and solved all quests except one - I can't find the Statue of Angel in the secret room that Heretic told me about. I have the key and I searched everywhere but I can't find the lock.
Are there anybody there who found it?

Also I found secret door that I don't know how to open - it is at the end of small dead end tunnel with a lot of barrels and boxes - to get there you need to jump from the elevator on the second floor ( eleveator goes from 1st floor to 3rd without stoping) Any ideas?

There is a lock on the wall in the hall before you enter the room with the monkeys and the hole in the floor.
