After last week's turgid slog this was fun, with only a few annoying obscurities that required Google research - chalcedony, ridotto, llano
Stumped by just one:
35a Free novel initially enjoyed by fashionable young man.
B?C?S?E?
Also, can anyone explain the 'E' in 16a:
Bug eerie E Sussex town picked up (6-6)
A: Creepy-crawly.
Eerie = creepy, Sussex town = Crawley, which is in West Sussex, so I don't see what the 'E' is doing.
