I discovered his Spenser novels last year and have been picking them up here and there from the library and second hand book shops.
The dialogue and characters are exquisite. Not huge complicated plots but somehow that really doesn't matter.
Sadly the author is dead and so I was rationing the books carefully.
Today I looked on Amazon and lots of them are on Kindle now for 50p to 60p. Many are very early ones I have come across before.
I am having a Spenser weekend.
