Less intriguing than the title infers, this is a district-by-district compilation of all the places associated with G&S and the Savoyards, with particular emphasis on buildings. Historical notes on the various places go broader than G&S, with particular attention to what went on during the Victorian era. As you can imagine, the notes on the theatre district are quite extensive. Plenty of B&W illustrations. I just wish the book had taken a lighter (more Gilbertian?) tone and hadn't been so hell-bent on faithful scholarship.
