Query: Suspicious -- read with caution

I don't know... things seem a little too tidy with Dr. Sachs' stories. His characters are always "charming" persons, with "delightful" senses of humor. The title character is such a person who also happens to be a brilliant musician and painter, whose paintings, by golly, morph with time to trace the onset of his disease. His second subject, a man who cannot form new memories (like the protagonist in a later Hollywood film, Memento) nonetheless finds himself getting bored solving old puzzles. (If you can't remember anything, how does boredom set in?) In another account, he assigns super-human powers of discernement to a room full of otherwise incapcitated patients as they laugh at a broadcast of a political figure that Sachs obviously doesn't like. Be careful how seriously you take these stories, nothing jazzes up a tall tale like a claim of authenticity.
