Oh boy have I found a great book!  Poet Jim Carroll was finishing this thing up when he passed away in 2009.  I have only read 73 pages so far but I recognize this as one of the greatest novels I have ever read.  A New York painter reacts strongly to some paintings by Velazquez, stumbles into Central Park and winds up in the looney bin where he finds some time to think straight.  Simple and magnificent.  What a damn great writer!  I think this will actually be the first novel I write a review of.  Now back to reading.
