Of course you all know that Thomas Tryon the author was first known as Tom Tryon, the actor? Quite handsome, too. If I knew that he died in 1991, I had forgotten it.

Maybe I should read Harvest Home some day.
I didn't know that, until I googled him a couple of days ago.
BTW, if anyone googles "Harvest Home" and arrives at Wikipedia, be forewarned that their entry describes the entire plot, start to finish, including tons of spoilers. Reading it was fun for me, as it brought back memories, but anyone who plans to ever read it should avoid Wikipedia.
