A single deck of cards tells a complete crime story. In this case, players take on the role of investigators: It is still quiet in the picturesque small town on the edge of the mountains. But that could soon change. A bomb has been found in the factory on the outskirts of town. So far, no one suspects what is brewing there. An explosion in the factory would certainly be a shock. But it could get much worse. Because hardly any of the residents have ever seriously questioned what is actually produced in that factory. Can you find the culprit? Can you uncover their true motive? Will you succeed in saving the town from a catastrophe? You can step into the roles of police officers, journalists, or engineers in this case. Each role allows for different solutions and enables you to play the game multiple times. But even though you have several chances: The town only has one!.
