I first read Trustee from the Tool Room as one of those Reader’s Digest Condensed Books. Wasn’t until later that I found the full version. Still my favorite.
When I was a kid, we had a bunch of the Reader’s Digest Condensed Books around the house, mostly from the late 50s. I read a lot of them, but after I read the unabridged version of one (The Last Angry Man, by Gerald Green) I never touched one again.
