Well, I think that would be the obvious sequel to the Doris whipping story. After all, she did spend more than three years in the Spandau Spinnhaus after her whipping so would have experienced all sorts of corporal punishments there. As it was behind closed doors, the historical record isn't quite as good unfortunately.Perhaps a fantasy about an old German Zuchthaus is appropriate for one of your future stories, if this theme interests you. For example, "A few days from the life of the Ludwigsburg House of Punishment."
One thing I am very excited about is that the Prussian State Archive is currently trialling a beta site which will eventually give full access to the collected daily edicts issued by Friedrich Wilhelm I. The scans and text are not yet accessible, but you can already search the index. For some reason, Doris's whipping order itself isn't there (but it has been in the public domain for almost two centuries), but we do have the appointment of her father to the post of Rector and Kantor at Potsdam in December 1729 -- she had lived in Potsdam for less than a month when she first got to know the Crown Prince -- her father's dismissal on 9 September 1730 (two days after the whipping), the appointment of his successor on 10 September 1730 and finally Doris's pardon issued in 1733. As a posthumous slander, the pardon is filed under the index category of "deserters - female accomplices", which is a crime she was almost certainly innocent of. Away from the Doris story, we have a fair number of other convictions of women to the Spinnhaus, including at least two unfaithful wives of noble officers (the Marquise de Ferrand in December 1729 and Margarethe von Wagner, the wife of Major von Wagner, in September 1729) -- there must be a story associated with that, but I can't find anything else about either of them online. Clearly, being sent to the Spinnhaus was a realistic risk for adulterous wives even if they had a higher status than Doris (who was a commoner).
