I’ll start by calling your attention to Michael Kreyling’s 2005 work The Novels of Ross Macdonald.
It was reading Professor Kreyling in the fall of 2013 that prompted me to start reassembling a collection of Macdonald. Once upon a time I had a complete collection, and in a great flurry of dispossessing myself of works that I thought I would not be returning to again I had gotten rid of all of them (after all, I had read each two or three times). Now I see that was a mistake. And now I am embarking on a major project of reading him again. He repays additional readings.
