Umineko: When They Cry Season 1 Episode 3

Dubious move

While attempting to figure out what had happened, the remaining guests discover that their radio is not working, effectively leaving them stranded on the island with the culprit until the typhoon passes. They also quickly discover that Kinzo has gone missing as well. Battler and the rest of the family come up with the theory that one of the eighteen people on the island is posing as Beatrice in an attempt to claim Kinzo's inheritance. The three primary suspects are the servants, who have access to the entire mansion; Natsuhi, who was the last person seen with Kinzo; and Eva, who has the most to gain from the murders. However, after a heated argument between Natsuhi and Eva, they are unable to come to a definitive answer and return to their rooms. Later, Eva and Hideyoshi are found to have been murdered in their locked room.
