Write down a name.
Name an action.
Pick an object.
Choose another name.
Now assemble these into a sentence.
The inspiration for this exercise is the game of Clue, in which players mix and match six characters, six objects, and nine locations to find out what really happened: “It was Miss Scarlet in the Library with the Revolver.” In your case, you might use elements from your WIP, childhood, or daily life.
When I tried this exercise, I used the characters and milieu of my novel. I rather liked this result:
Rebekka kissed Harald with the piano.
Another suggested a new scene for the book:
Hanna walked with Greta through the field.
Try it out for yourself and let me know what you come up with!
