What exactly was on this recording device? When Matthias turned it on, he heard the voices of an old woman and an old man conversing. But the old man's voice wasn't his father in law's, but rather his father in law's personal lawyer. Listening intently to the conversation, his brow furrowed and his right fist clenched as he heard a single word that was the key to his father-in-law's murder.
Matthias remembered himself talking to his father-in-law earlier. His father in law told him to be wary of everyone around him because his closest people all this time only wore masks. Matthias is also increasingly suspicious that the accident that happened to his wife two years ago was caused by the same person when he heard the old woman's cruel words.
