About this course

Course summary: Build believable, fair, emotionally engaging crime and mystery stories. This 40-lesson Writer’s University course teaches subgenres and reader expectations; criminal behavior and character motivation; primary and secondary research; legal and forensic accuracy; ethical portrayals; setting; detective and suspect development; clue design; red herrings; suspense; dialogue; and revision. Each lesson includes objectives, core instruction, a worked craft demonstration, a practical writing lab, and self-check answers. Complete a researched crime-story portfolio and evaluate it against a 100-point rubric.


Course overview: Intended for beginning and developing fiction writers. A story idea is helpful but not required. The course uses invented examples to teach craft, never to suggest that a fictional procedure has been validated as real-world law or science. Workload: about 3–5 hours per module plus capstone drafting.


Learning outcomes: Identify a subgenre and reader contract; formulate a solvable central crime; portray motive without stigma; document research and uncertainty; design investigative and forensic scenes with realistic limitations; construct a clue chain and earned reveal; control suspense and viewpoint; and revise based on targeted reader feedback.


Portfolio and completion: Complete 40 lesson labs and retain the revised artifacts as a writer’s casebook. Each lesson works independently in Writer’s University. The final assessed portfolio appears in Lesson 10.4 with criteria totaling 100 points.


AI Writing Partner: Optional AI can test whether a timeline is consistent, role-play a skeptical first reader, or suggest alternative scene arrangements. Never treat its invented legal or forensic detail as research. Verify with suitable sources and keep the author in charge of the story and all final decisions.
