In A Tale of Two Cities, why might the author have skipped over years since several years pass between Chapter 21 and Chapter 24?
How does the passing of time contribute to the longer effect of the novel?
During those four years, things in both cities were developing but the growth was relatively slow-moving. In London, Charles and his family were growing. They had two children, and one of them, their son, died. Nothing much changed with any of the other London characters, either. Life was good and progressing as most lives do.
The same is true of events in Paris. It's true that the Revolution had begun, but it was moving at a crawl--like a slow-moving virus which covers ground at its own pace but does so thoroughly.
By the time Dickens takes us back to the action, everything is ripe for the coming events.
