Same narrator, different stories

Let them figure it out. Readers are a lot smarter than we sometimes give them credit for.

I agree with nevada. There is no reason to mention any other stories in a cover letter. As long as the stories stand alone, there is no need. If they don't stand alone, then you shouldn't be submitting them as short stories anyway.

So-called "linked stories" or "novel-in-stories" collections are common these days. Some folks are convinced that the only way for a first-time writer to sell a short story collection is if the stories are all connected. In other words, there's nothing wrong with writing a series of stories with the same characters.

Oh, one more point. I don't know of any magazines that publish more than one story by a writer in the same issue. So I don't think you need to worry about that.

Joseph Conrad used this device numerous times. Not a bad example to follow.

And, of course, you have innumerable examples of genre novel series, especially mysteries, like the Nero Wolfe novels and stories by Rex Stout, and the Travis McGee novels by John D. MacDonald.

As long as you don't have to have read one to understand the other, don't bother.

It doesn't matter if you're reusing the narrator. I do it all the time.
