     I stood outside the door for a space, letting “I dare not” wait upon “I would”, as Jeeves tells me cats do in adages, then turned the handle softly, pushed – also softly – and, carrying on into the interior, found myself confronted by a girl in housemaid's costume who put a hand to her throat like somebody in a play and leaped several inches in the direction of the ceiling. “Coo!” she said, having returned to terra firma and taken aboard a spot of breath. “You gave me a start, sir!” [...] “If you cast an eye on him, you will see that he's asleep now.” “Coo! So he is.”
