Abandon your promise
Horrid stories are told of the vengeance of the dead. But they're, well, dead. How much harm can they do?
Meet the Gracious Widow in Spite
Unlocks: Courier of the Dead 2
You have arranged to deliver the dying spirit's message to the Gracious Widow. Let's hope she likes the message.
Abandon your commission
Something about this unnerves you. Perhaps it's the commerce with the dead. Perhaps it's the Widow's occasional reputation for dipping living men in hot tallow. In any case, you are prepared to risk the vengeance of the ghost you betrayed.
Deliver the message
The room where you meet the Widow is utterly black. You hear a chair creak as she settles herself. You explain the situation. There is a long pause. 'Whisper the words to me,' she says.
(A matter of luck: it could go either way.)
