In the little steps

When one of the victims was found poisoned on the cold tile floor of the swimming pool, and another was stuffed alive into the freezer of the cake shop, your murder club immediately understood that these peculiar murders must somehow be linked. The police aren’t willing to believe, save for one detective, that there is a serial killer behind the crimes, so only you can find the connection and catch the murderer. The newest member of your group, Usva Varjo who works as a psychologist, has a theory about the killer. Usva was supposed to present the theory at the same time to both you and the commissioner in charge of the case, but there is no sign of Usva. When you find a mobile dropped on the doormat outside Usva’s apartment, your worst suspicions start to come true. Can you determine the whereabouts of the murderer and save Usva on time from the bloody pastimes of the serial killer?
