The House in Fata Morgana (2012)

Read the original English PC novel for the mansion's complete central mystery and its resolution. The linked tragedies are stages in one finished work, so keep reading beyond the apparent early stopping points. A Requiem for Innocence and other related stories are separate additions; this purchase does not collect the whole series. Its value is a sustained gothic narrative with relatively few choices, and its abuse and violence are emotionally severe.
