The Four Feathers by A.E.W. Mason

Mrs. Adair, on her side, asked for no explanations. She was naturally, behind her pale and placid countenance, a woman of a tortuous and intriguing mind. She preferred to look through a keyhole even when she could walk straight in at the door; and knowledge which could be gained by a little maneuvering was always more desirable and precious in her eyes than any information which a simple question would elicit. She avoided, indeed, the direct question on a perverted sort of principle, and she thought a day very well spent if at the close of it she had outwitted a companion into telling her spontaneously some trivial and unimportant piece of news which a straightforward request would have at once secured for her at breakfast-time.

Therefore, though she was mystified by the little white feather upon which Ethne seemed to set so much store, and wondered at the good news of Harry Feversham which Captain Willoughby had brought, and vainly puzzled her brains in conjecture as to what in the world could have happened on that night at Ramelton so many years ago, she betrayed nothing whatever of her perplexity all through lunch; on the contrary, she plied her guest with conversation upon indifferent topics. Mrs. Adair could be good company when she chose, and she chose now. But it was not to any purpose.
