Merton of the Movies, by Harry Leon Wilson

The book begins: At the very beginning of the tale there comes a moment of puzzled hesitation. One way of approach is set beside another for choice, and a third contrived for better choice. Still the puzzle persists, all because the one precisely right way might seem-shall we say intense, high keyed, clamorous? Yet if one way is the only right way, why pause? Courage! Slightly dazed, though certain, let us be on, into the shrill thick of it.
