Story based on The Adventure of the Dying Detective

I just read a retelling of The Adventures of the Dying Detective in the BBC 'verse and I was reminded of an old story taking place during the case. I remember very little but I'd love to read it again. It takes place in Victorian times and I'm pretty sure it's Holmes/Watson slash or at least pre-slash. I only remember part of it. Watson was very hurt that Holmes didn't trust him as a doctor and believed that everything Holmes had said was right, so he decided to leave. I'm not sure what happened to him then. Holmes notices something is wrong when Watson doesn't return. I think he went looking for him?

Does this seem familiar?
