Dorothy L Sayers' Gaudy Night is one of those books which I find I can read and re-read time and time again - and get something new out of it on every occasion. This time I read it for its commentary on personal integrity and the consequences of crime on the perpetrator and on those connected with them. I also noticed how the clues are built up, layer upon layer as well as the red herrings. It is an object lesson in how to plot a crime novel and it actually doesn't matter that there is no murder.
I then started reading Murder Must Advertise which I haven't read for about 30 years and I am finding it every bit as good as I remembered it to be. Peter Wimsey takes a job in an advertising agency for reasons which are not at first revealed. The advertising background is authentic as Sayers herself worked at an advertising agency for a time. The book has some trenchant comments to make about the ethics of advertising which are still valid today.
