This keeps getting weirder and weirder, and you get more and more concerned. Obviously Madeleine is about to meet someone at a given place at a given time. And what's up with having her diary in Trello? If you could only find out the time and the place, you should have enough intel to finally get the police to do something.
You write down the most important information in a document and start investigating what you have (open the PDF). You have no time to lose – the sooner you find the time and the place, the bigger the chance of finding Madeleine and the machine before it is too late.
When you know the time, date and place, you can move forward to contact the police.
Before you contact the police: download the notes (PDF) and find the time, date and place.
