I hadn't realised that about the publication order (Wikipedia unhelpfully failed to list publication dates for anything apart from the Dimsie books). Are there other St Bride's books, though? I assumed there must be as there is a very mid-series feel to Nancy at St Bride's, with references to things about the characters other than Nancy which seem to assume that readers are already familiar with them.

I think I'd managed to pick up that the Anti-Soppists were from the Dimsie books - I'd certainly be interested in trying a few more if you're happy to lend them.
