Sophie

Intro A few decades into the future, humanity is now establishing space colonies around the Solar System. You are at a colony on Mars. Your colony is made up of three dozen people, all of them specialists in various fields - an engineer/mechanic; a couple IT experts; a doctor and assistant nurse; various scientists (biologist, geologist, chemist, etc); you and Sophie are the Space Marshals at the colony, responsible for order and security. You two are also romantically involved, but have to keep quiet about it, as fraternizing at the colony is strictly against regulations. Now, the quiet routine at the colony is shattered, when one of the colonists is found murdered. Any outside help is many light years away. All of you, including the killer, are stuck together in the colony pod station - the air outside is not breathable without a space suit. So, it is up to you two to figure out what happened and stop the murderer.
