The Heart of the Beast The Secret of the Old Manor #3

This house hides many secrets. Even the person who built it does not know them all. Secret passages, basements, and most importantly – the cave lying at its foundation, where a silver heart beats… the heart of the beast. Random people do not enter this house. Architect August Berg, teacher Sofia, who is far from being as simple as she seems at first glance, and Ilya – a boy resembling a wolf cub – they have all gathered here for a reason. The house has chosen them and is preparing a trial for each of them.
