In The Incident of the Letter, Mr. Utterson visits Henry Jekyll, who promises to break with Hyde and entrusts him with a letter apparently signed by Hyde. Poole’s account of deliveries and Mr. Guest’s comparison of handwriting deepen Utterson’s suspicions, leading him to believe that Jekyll forges the letter to protect a murderer.
