A Ghost Named Cashew by Ldostal

The year is 1882, but you have been dead for five decades. In life, your lavish house was your only comfort from a painful marriage and an unfeeling world. In death, your house is your purgatory. However, when two people move into your home, oblivious to your suffering, your house turns into a hell. Your only hope rests in the family cat, who is aware of your presence. But can you harness his help in time to escape eternal torment?
