"Shibumi" is a fun read, and you might also want to check out "The Loo Sanction" and "The Eiger Sanction," the latter of which was made into a film directed by Clint Eastwood, who also starred.
Not to nit-pick, but if you're going to the bookstore to pick up a copy of any of them, it might be helpful in locating the correct shelf to know that the author's pseudonym is Trevanian, with an "e."
His real name was Dr. Rodney Whitaker, who was a professor of film at the University of Texas Austin, Bucknell, Penn State, and Emerson College in Boston. He also wrote "The Summer of Katya," "The Main," and "The Crazyladies of Pearl Street," among other titles.
Whitaker served in the navy during the Korean War era, and, once his literary reputation was established, lived a very reclusive and private life in the Basque country of France for many years.
Trevanian/Whitaker passed away last December.
Thanks for that info, Jack. Sorry to hear he's gone. Yes, I'll be looking for more of his works. Brilliant writer -- and humorist as well.
I liked "The Loo Sanction" and "The Eiger Sanction," but I never could get through "Shibumi." Usually, I like all books (or none) by an author.
