Property inspection that turned spooky!

Something didn't feel quite right and I thought there might be a carbon monoxide issue in the house, so I opened the windows and doors to allow the air to flow through the property to give me some more oxygen. 
 
I continued to feel uneasy in the property, so went outside to inspect the roof and structure, while I hoped I would be able to pull myself together.
 
When I came back inside to set up my ladders and get into the loft, I placed my iPad (which I use to data capture in the property) on the side with the screen lock on. I entered the loft and had a good look around. I found some damp to the chimney stack and some timber issues, so climbed back down the ladder to get my iPad to record what I had found. 
 
When picking up the iPad, I had a massive shock. 
 
“Bob.” was written on the screen! 
 
I spoke to the neighbour and they confirmed that an elderly lady had lived in the property for 50 years and they didn't know a Bob who lived there. So the identity of Bob remains a mystery.
 
Unfortunately Bob didn't help me to write up the rest of my survey!
 
Perhaps he found some comfort in me telling him:  "Don't worry Bob, I am a surveyor not a slayer!”.
