Short answer
This is one of the best entry points in this cluster. A strong B1 learner can use its short length as a supported challenge; B2 readers should follow the events comfortably but will still need help with puns and historical references. Difficulty comes less from rare vocabulary than from language play.
Vocabulary profile
The bars show the share of running word tokens—not the share of unique dictionary entries. Common words repeat often, so token coverage is the more useful signal for how frequently a learner may meet unfamiliar language while reading.
These are TeakReader frequency-based vocabulary bands, not official CEFR assignments for every word or an official CEFR certification of the book. They are most useful as comparative reading signals.

Transparent methodology
We downloaded the UTF-8 plain-text edition from Project Gutenberg ebook 11, removed the standard Gutenberg header and footer, lowercased English word tokens, and matched them against the same ranked frequency data TeakReader uses for vocabulary analysis. We then combined token coverage with editorial review of syntax, narration, dialect, historical context, and wordplay.
Vocabulary coverage is informative but not a complete readability score. Research on reading comprehension commonly distinguishes knowing most running words from understanding every sentence; syntax and background knowledge still matter. See this Cambridge overview of lexical coverage research for context.
FAQ
We recommend Strong B1 to B2 for the original text. Short enough for an ambitious intermediate learner, but puns, nonsense, and Victorian expressions make B2 the more comfortable level. This is an editorial estimate based on vocabulary coverage and literary features, not an official CEFR rating.
