Pickering Station, Antarctica: A place of science, knowledge, and deep isolation. When the last plane leaves for the winter, you and your colleagues may as well be on Mars. At least this winter-over has gone well so far — or as well as can be expected with a dozen or so eccentrics locked up together.

But then someone turns up dead...

You have ten days until the next plane arrives and law enforcement takes over the investigation, and by then the perpetrator will have covered their tracks. Can you bring them to justice first? And can you keep your sanity in the process?
