Parking lots are constantly full of vehicles, day and night, but when a vehicle appears abandoned in the middle of the city square, things get a little bit suspicious. It is late at night, there is hardly anyone in the square, and Detective Mary receives an anonymous call about an abandoned vehicle left there.
Allegedly, the vehicle had been standing there for a long time, and no one got out or entered it. Usually, if someone is in the square with a vehicle, they leave very quickly, after finishing some short work, but not in this case. Mary, even though it is very late, decides to head to the square immediately to shed light on the mystery of the abandoned vehicle. She tries to find witnesses who can tell her who drove the vehicle or why it was left there, but no one saw anything.
Mary tries to find enough evidence and hopes that with them she will be able to find out what happened this evening and where the passengers of the vehicle might be. It is also debatable what is hidden in that vehicle, but let's go step by step.
