Adult PC Game: A Hand in the Darkness Final by Ertal Games Archive

The story follows Alex White, the youngest member of a large family and hence always rather overprotected, into his new stage in life moving to an exclusive boarding school,
St. Michaels, during the Edwardian era.
There he will meet some friends: the always cheerful and helpful Monty, the shy and clever Rick, the snob and troublemaker Damian.
But he will also face an unexpected danger.
And perhaps, who knows? He will even find true love. It's up to you to decide if Alex will reach a happy ending or will leave St.Michaels with a broken heart… or maybe even worse.​
