[How] come an author can write one good mystery novel and then turn out [The Loo Sanction,] a disaster? Unless I was too charitable when I judged Trevanian's The Eiger Sanction, there was much to recommend it. This one should have been left at the nearest loo. And a loo, in case you don't know, is an English term for w.c. Which reminds me: If Mr. Trevanian intends to locate any more stories in London, he should do more careful research on English life or get himself an English editor.
