It's "J.D. Salinger" all over again when Frasier (Kelsey Grammer) and Niles (David Hyde Pierce) spot T.H. Houghton (Robert Prosky), a famous -- and famously reclusive -- author who published one best-selling classic before completely disappearing from view. Alas, once spotted, Houghton vanishes again, sending the Crane brothers on a frantic search to relocate their literary idol. As it turns out, however, it is another Crane -- Martin (John Mahoney) by name -- who stumbles upon the elusive Houghton by accident.
