Shaun Usher has built a fascinating career reading other peoples' mail.
Best of all, he's not about to be arrested for it, since he compiles letters from people no longer alive.
Usher visited a couple of years ago with the first Letters of Note; he's back with a second volume.
Highlights include letters written by J.K. Rowling, Che Guevara, and Marge Simpson. Marge Simpson? Shaun Usher gets on the phone to explain.
