Personally I have always been an Agatha the Christie fan. My first encounter with Dorothy L. Sayers was the Mobile Mystery Theater series showing on PBS.
Naturally the TV media cannot fill in all the details that you would pick up from reading the book. So I read the book. This added more depth to the story, but now I appreciate Dorothy L. Sayers more than Agatha Christie. But Dorothy not only fleshes her characters out better but her side trips into philosophy and psychology make the story that much more interesting. And just when you say, "what is the relevance to this conversation?" it is wrapped up in the final solution.
This is the first of a fourth book series. The story is complete and can be used as a stand-alone story.
The notorious Harriet Vane is on trial for poisoning her previous live in lover. Naturally Lord Peter Wimsey falling in love with her, is determined that she is innocent and will prove this. To save her repartition he must fined the real culprit (if there is one), because if Harriet gets off on a technicality, she will always be under suspicion.have his Carcase
