Murder at the Pit

I was in a movie with a small bit part. It was something like Journey to the center of the earth or a remake of the abyss. We were filming at an old cave that had a deep drop. I was reviewing some photography and one actress who had few images the night before suddenly had over 100,000 images. Turns out she had died by falling in the pit. Sherlock Holmes didn't think it was an accident. He decided to show up in disguise and start investigating. I was the only one who knew he was sneaking around but I didn't know what he looked like. Everyone was freaked out but trying to soldier on. Sherlock started interviewing everyone trying to find the murder and I freaked out because even though I hadn't killed the actress Sherlock always discovers something embarrassing about you and I didn't want him airing my dirty laundry. I panicked and woke up.
