The King in Yellow by Raymond Chandler

Quillan, head day clerk and assistant manager of the Carlton Hotel, was on night duty, because Millar, the night auditor, was off for a week. It was half-past one and things were dead and Quillan was bored. He had done everything there was to do long ago, because he had been a hotel man for twenty years and there was nothing to it.

The night porter had finished cleaning up and was in his room beside the elevator bank. One elevator was lighted and open, as usual. The main lobby had been tidied up and the lights had been properly dimmed. Everything was exactly as usual.
