Paul Stones was an extraordinary inventor who led a quiet life.

One evening, he called me in a panic and asked me to meet him in a small café in the city centre.
He needed my help to protect his latest creation.
An invention capable of revolutionising the daily lives of millions of people because "they" were after him and "they" were prepared to do anything to get their hands on it.

I tried to reassure him as best I could before dropping him off at home. The next day at the office I got a voicemail. It was Paul.
" They've found me... I'm not telling them anything! I know the line isn't safe, so I can't explain in detail. Follow the Light is the key to protecting my invention. Take a quick look on my desk and you'll find a list of people who can help you....... "

I knew straight away that I wouldn't be able to solve this puzzle without help.

If you're reading this message, it means you're on this list. I need your help urgently.
There's one thing that strikes me about Paul's message: " Follow the Light ". Perhaps this is an avenue worth exploring...
