You followed Elle to the next room where the orb had said you would find the safe. It was some sort of gallery room. The walls were covered in paintings. Eventually Elle found a picture of a woman with two Basset hounds. She called you over and you lifted the picture off the wall Sure enough there was a safe underneath.
However when you went to dial the combination you realised the safe was not locked. You opened the door and found it was totally empty.
"He lied to us. There is no diamond necklace in here"
"We don't know that he lied. Maybe it was here but was taken by someone since Eric was put in the orb" Elle suggested.
"More likely he was lying. I don't like this place. It's giving me the creeps. Let's find the others and get out of here"
"No" said your girlfriend "We can't just leave Eric. Can you imagine being stuck with no body? It must be horrible for him. We have to help"
"Let's call the police or something. It's his problem not ours"
"But he will reward us if we help him"
"If you can believe him"
"Well I do and I'm going to help him" with that Elle walked off returning to the other room.
You paused for 20 seconds before reluctantly following her.
