As it turns out, reading did the trick. I'm not quite done with it yet, but if you like yourself a literary mystery, may I recommend Generation Loss by Elizabeth Hand? The jacket flap: "Patricia Highsmith meets Patti Smith when a down-and-out photographer and relic of the '70s NYC punk scene travels to an island off Maine in search of a reclusive and iconic artist." It's gritty and it is good.
Speaking of gritty--or kind of raspy and adenoidal, as the case may be--yours truly has been on the radio for Practically Perfect. Both Debbie Mandel and Deborah Harper have these fascinating shows. Have a listen, if you're so inclined, here, and here.
