When the final volume of "The Great Detective Hercule Poirot" was released, Silver Blue Books made a lot of effort in promoting it.
Knowing full well that the Poirot series was about to end, they published its last volume...
But it's different this time.
Perhaps the lesson from the last time was too profound, or maybe there were other concerns.
Anyway, Silver Blue Books didn't do any flashy endings or gimmicks for the promotion of "The Final Case" this time.
The company didn't even inform the readers in advance that this story represents the conclusion of the Holmes series, but, unusually, published the last volume of the Holmes series quietly--
Everything was as calm as ever.
Some readers didn't discover the new book from "The Great Detective Sherlock Holmes" until they walked into the bookstore.
With surprise, they spread the news to others!
