Crimes are committed, but not all of them are solved and the criminals remain unpunished. Dylan and Grace are brother and sister, they came to the town where their grandfather lived, who passed away a year ago. The grandchildren suspect it was a murder, but the investigation, which lasted almost a year, was closed for lack of evidence. The heroes do not agree with such a conclusion of the case, they gave the opportunity for justice to work. And now they want to get to the bottom of it themselves. They need to know exactly how it happened and why. My grandfather was in good health, but then suddenly there was a heart attack and he died. Not long before that, an unknown guest had found him out and they drank tea. And soon after he left, grandfather passed away. It looks like poisoning, but the poison was not found either in the cup or in the body. But still, something is wrong here, you need to find this person and then the thread will lead to the truth in Forgotten Evidence.
