Assuming you mean the character Richard Brunton from the short story 'The Musgrave Ritual,' the butler, Brunton, did not have an assistant (unless you count his personal project), but the second housemaid, Rachel Howells, must be who you are enquiring about since the two of them were romantically linked.
"Of the woman [, Rachel Howells,] nothing was ever heard, and the probability is that she got away out of England, and carried herself, and the memory of her crime, to some land beyond the seas." -- Sherlock Holmes
