## What happens

Watson escorts Miss Morstan home, reflecting on his growing feelings for her and the barrier of the Agra treasure. He then retrieves Toby from Mr. Sherman, returns to Pondicherry Lodge, and assists Holmes in analyzing the crime scene. Holmes deduces the involvement of Jonathan Small and a barefoot accomplice, and they set off with Toby to track the suspects.
