In "Seventy-Seven Clocks" by Christopher Fowler, the imagery used to describe the clouds creates a vivid picture of a nighttime scene. The phrase compares the clouds to ink spreading in water, suggesting a sense of fluidity and transformation. This metaphor evokes a feeling of mystery and the beauty of the night, as the darkness unfolds in an artistic way.

This literary technique not only enhances the aesthetic quality of the scene but also invites readers to explore the deeper themes present in the narrative. The contrast between light and dark, along with the fluidity of the clouds, may reflect the complexities of the characters' lives as they navigate the challenges and enigmas within the story.
