After accidentally bumping into someone in a store who turned out to be your old best friend Sherlock... you're now in the park with him.

Sherlock left back then, just like that, without warning, without a goodbye, without a farewell... In all these years, not even a single letter reached you... The only sign of life you had from him were his newspaper clippings.

You walk side by side through the park, talking, laughing, and enjoying the great weather.

"Would my letters have interested you?" he asks suddenly, looking down the road.
