Nolan's Scenario
This hint is only useful if you are playing the scenario as Nolan. To finish the scenario, the first thing you should do is go up stairs into the bedroom and look in the closet twice. The first time will hint at something being there, the second time you will find the statue.
Then go into the kitchen and look at the mask on the wall, this will confirm the location of the Barrows mansion. After the confirmation message, the mask will come alive. Use the vase on the table and throw it at the mask.
Finally, go to the laundry room and get the powdered soap in the cabinet across from the washing machine. Go back into the living room and out the sliding glass door in back, toss the soap into the dogs eyes to escape.
