In my twenties (or was it thirties?) I read many of the American crime/ thriller novels of Ross Macdonald and John D MacDonald. Both authors are highly regarded and I remember much enjoying the books.
Decades later, on one of my occasional clear-outs, I disposed of their books and those of other authors. I remember thinking twice about getting rid of the John D MacDonald books because they had such fabulous covers. Interestingly I’ve started following a blog devoted to his book covers, and it was this that’s motivated me to re-read some of the two authors’ books. I’m sure the image on the right is from the range I had once owned but I can’t find images of the other books in that range.
I’ve only managed to find two ebooks by RM or JDM at my local on-line library. RM’s The Dark Tunnel was one of his early novels – and it shows! Absolutely terrible, though it won’t stop me looking out for his later works. However, JDM’s Nightmare in Pink is a superb read.

Thanks for the shout out, Mike. I have fun posting the covers and appreciate knowing others enjoy them.
