Serendipity works in mysterious ways. In 1998, Walter Kirn, then a struggling writer, decided, on a lark, to drive a dog from Montana to New York. He then struck up what would become a fifteen-year friendship with the dog’s owner, the eccentric, wealthy, generous Clark Rockefeller. That wasn’t the lucky part, though: “Rockefeller” was in fact Christian Karl Gerhartsreiter, a con man and murderer who was eventually caught by the FBI and who is now serving a life sentence in prison. What’s lucky is that the person who witnessed Gerhartsreiter’s downfall was a writer as perceptive, as honest, and as plainly talented as Kirn — who emerged from the ordeal mostly unscathed and is now known for acclaimed novels including Up in the Air and Thumbsucker. Kirn’s new book, Blood Will Out, comes with the pacing of a true-crime thriller (which it is) and the unflinching self-examination of a really, really good memoir (which it also is). Hear him read from it at Morrison Library (UC Berkeley campus) as part of the library’s “Story Hour” series.
