I think we should start from the bottom and work our way up so I suggest 'Irene Iddesleigh' by the irrascible Amanda McKittrick Ros.
She was a great lady and invented so much that has developed the novel in English even if she was Irish.
I collect her first editions especially with her hand written notations. She was a wonderful lady.
Espouse elucidation and eschew obfuscation!
