I'm just reading Murray Leinster's A Logic Named Joe - it's a collection of short stories/novelettes that, to me, feel as though they were written in a more innocent time. I'm often chuckling or laughing as I read.
It's in the Baen free library too...

It'll have me reading more of his work in the future.
