Sherlock Holmes pastiche. He encounters a female (and in fact actively feminist) heiress in his retirement keeping bees up on the moors, and takes her on as his apprentice.

It's structured as episodes retold (with a framing story about how the author got the manuscript, but never mind that); the first few are their meeting and setting the basis of their relationship, then he starts involving her in his cases.

There's a bit of a feel of "Mary Sue" to it, but it doesn't go over the top; they don't ever end up in bed, for example, and Holmes' attraction to her is only referred to obliquely.

It ended up having a rather pleasant feel, for me, though I'm not rushing out to locate the rest of them (two more I believe).
