About this reading order
Books are listed in the series' own numbering, which for Lady Hardcastle is also the best order to read them in. Novellas and short stories sit between the novels they follow, numbered the way the publisher numbers them (3.5 comes after book 3). They are optional — you can skip them without missing the main story. Years are first publication where we could confirm it, and otherwise the first audiobook release.
