Crime Fiction Co-Writer

Remote Contract Crime Fiction Cowriter

Mary Stone Publishing is seeking an experienced, creative remote contract cowriter to collaborate on full-length crime fiction novels. Working from detailed outlines, you’ll write compelling stories featuring memorable characters, suspenseful plots, unexpected twists, and authentic law enforcement elements while collaborating closely with our editorial team.

The ideal candidate has a strong understanding of the crime fiction, mystery, thriller, and suspense genres and can consistently produce engaging, high-quality manuscripts that captivate readers. This is a long-term remote contract opportunity with ongoing assignments for writers who thrive in a collaborative, deadline-driven environment.

Successful candidates have a deep understanding of crime fiction—from gripping suspense and complex character arcs to jaw-dropping reveals. If you have a sharp analytical mind, a passion for dark, twisted storytelling, and the ability to elevate a story to its full potential, we’d love to hear from you.

Scope of Work: Bring Crime Fiction to Life

As a cowriter for Mary Stone Publishing, you will collaborate closely with your assigned Developmental Editor (DE) and other team members using our online platform. You’ll follow detailed series and book outlines, bringing your storytelling skills to an established framework while adding your unique voice. Training on our style, expectations, and workflow will be provided.

• Creative Execution: Write approximately 70,000-word crime fiction novels from detailed outlines. While the structure, major twists, and story arc are predetermined, you’ll have the creative freedom to bring scenes and characters to life in an immersive and compelling way. All work should be self-edited and proofread before submission.
• Research & Accuracy: Use your knowledge of police/FBI procedures, forensic science, and other relevant sources to ensure procedural accuracy and authenticity.
• Critiques & Revisions: Submit each novel in four 17,500-word sections for developmental review. You’ll receive detailed feedback throughout the writing process and implement revisions to strengthen pacing, suspense, character development, and overall story quality. After completion, the manuscript will move through our editorial process, including developmental, line, copy, style, and quality control editing. Writers are expected to complete revisions at each stage until the manuscript meets MSP’s quality standards.
• Series Continuity: Maintain character consistency by referencing the Master Character List, ensuring continuity throughout each book and series.
• Communication: Communicate professionally, meet deadlines, and remain open to editorial feedback while collaborating with the team.
• Technical Proficiency: Be proficient with Microsoft Word’s Track Changes and commenting features and write according to the Chicago Manual of Style, the Mary Stone Publishing Style Guide, and standard U.S. English conventions.
