* "The Speckled Band" is a Sherlock Holmes story by Sir Arthur Conan Doyle. In this story, John (not "John A") is the name of the brother of Helen Stoner, the victim. He dies from a venomous snake bite, but there is no mention of a "Recoil" in the story.
* The "Recoil" is a term that might be referencing a book or a concept, but it's not connected to Sherlock Holmes or "The Speckled Band".
To help me understand your question, please clarify the following:
* What is the "Recoil" you're referring to? Is it a book, a movie, or another Sherlock Holmes story?
* What is the connection you're drawing between "The Speckled Band" and this "Recoil"?
Once you provide more context, I can give you a more accurate and helpful answer.
