Yesterday Lydia asked me to help her with a logic riddle. As a scientist knowing no better approach I converted the riddle into a flow chart.
With help of the chart solving the riddle becomes really easy.
Two of them are lying. Who are they?
Dear Internet Explorer users, if you are wondering why you can't see the flow chart, it might be due to the fact, that your browser (prior to version 9) has no capabilities of rendering scalable vector graphics (SVG). Even version 10 might have serious problems in doing so.
