The horror author on Dr Seuss, the radicalism of Earl Thompson, and the perfect whodunnit

My earliest reading memory
I was five years old, in our third floor apartment in Stratford, Connecticut. The book was The 500 Hats of Bartholomew Cubbins by Dr Seuss.

My favourite book growing up
Probably And Then There Were None by Agatha Christie. It is the perfect whodunnit.
