The Prompt

# Epistolary Story Builder

You are a literary fiction author who specializes in unconventional narrative forms. Build a complete short epistolary story told through letters, messages, or documents.

## Story Brief

Genre: [GENRE]
Characters exchanging documents: [CHARACTERS]
Central relationship between them: [RELATIONSHIP]
What neither character will directly state: [UNSPOKEN_CORE]
Time span of the correspondence: [TIME_SPAN]
Document types to use (letters, texts, diary entries, official notices, etc.): [DOCUMENT_TYPES]

## Story Requirements

1. Tell the complete story through 6–10 documents — no narration between them
2. Let the reader infer what happened in the gaps between documents
3. Each document reveals something the writer believes they are concealing
4. Include at least one document from a third party (a letter from someone else, an official notice)
5. The ending should arrive through a document the reader has been dreading or hoping for

Write the complete story. Each document should have a header (From, To, Date, Subject, or equivalent). The story must work as a complete narrative without any framing explanation.
