A short, fast book built as a mystery, with a secret held back until the last two chapters. The language is Victorian, but the chapters are brief and the dread works even if you know the twist. Four and a half out of five (draft). Read it if: you want a short classic that reads like a mystery; you like stories where the secret is delayed and told in documents; you are curious about double lives and respectability. Skip it if: you expect a monster story with the transformation in the middle: the book mostly shows it late and tells it; long victorian sentences wear you out; you want much action: most scenes are conversations.

A London lawyer, Mr. Utterson, grows alarmed by his friend Dr. Henry Jekyll's strange bond with a small, hated man named Edward Hyde, and starts to investigate. A violent crime, a will and a run of sealed letters push him toward the truth, which the book holds back until its last two chapters.
Robert Louis Stevenson wrote it. It was first published in January 1886 by Longmans, Green and Company in London, as reported by Wikipedia and the Oxford Text Archive, as of November 2026. We read the Project Gutenberg text, ebook number 43.
The Gutenberg text has ten chapters. By our count, the ten chapters run to about 25,600 words, a short book you can read in a few sittings. The last two chapters are long documents, together about 38 percent of the text.
By our count, the lawyer Mr. Utterson is named 131 times, more than Jekyll (96) or Hyde (98). Most of the book follows him as he investigates, and the last two chapters are letters he reads.
The sentences are long and the language is Victorian, but the plot moves fast and the chapters are short. The first chapter is a story told by one man to another on a walk, so you get the style quickly.
It is more eerie than gory. The dread comes from what people feel around Hyde, and from a few violent moments. It has no jump scares, and most of the horror is told, not shown.
