I enjoyed the Cazalets on Radio Four and was then motivated to buy the books so I could read them at leisure.
I assume this edition has been especially printed to co-incide with the broadcast but the quality of the print is so bad as to make it literally unreadable. It uses a thick blobby font that hardly seems to separate the words. As I bought it online, I had no way of knowing this before buying. I asked friends' opinions and they agreed that the print quality would make it unreadable.
