I’m writing with a steel-nibbed dip pen, model number 137B, from Hughes & Sons Ltd. of Birmingham. I requested the Extra Fine Tip, partly to save money on paper, and partly so that I could jab my thumb with it and draw blood. The brown smear across the top of this page can be tested in any twenty-first-century DNA lab. Compare the results to what is on file in my personnel record at DODO HQ and you will know that I am a woman of your era, writing in the middle of the nineteenth century.
