Возвращение Шерлока Холмса (The Return of Sherlock Holmes)

Holmes's return was unexpected after his apparent death; I'm curious about what motivated Doyle to revive such an iconic character and how it shaped the stories.

While I love the cleverness, some deductions seemed overly intricate, making me wonder if Doyle wanted to showcase Holmes's brilliance or add a layer of complexity.

The tone in this collection felt slightly different—more reflective or mature. Did anyone else notice a shift, and what do you think caused it?
