The Freaks of Mayfair by E.F. Benson — Read

UNDYING INTEREST IN THINGS ABSTRUSE, experimental, or charlatanish keeps Mrs. Weston perennially young. She has a small pink husband, who desires nothing more of life than to be allowed a room to himself, regular meals, a little walk after lunch followed by a nap at his club, and a quantity of morning and evening papers to read. Indeed it may be said of him that the morning and evening papers were his first day and will certainly be his last, for he is the sort of person who will die suddenly and quietly after dinner in his arm-chair. All those simple needs are easily supplied him, for when, for reasons to be subsequently mentioned, he cannot get regular meals at home he procures them at the Carlton grill-room.

The two have no children, and her husband being so simply provided for, Mrs. Weston has plenty of leisure to pursue her own weird life. She began, as most students of the faddish side of life do, by using her excellent physical health as a starting-point for hypochondria, and proceeded to cure herself of imaginary ailments with such ruthless ferocity that if she had not stopped in time, she might really have become ill. As it was, she arrested her downward course of healing before it had done anything more than make her thin, and took to another fad. But she resumed her pleasant plumpness when she embraced spiritualism, for spiritualism for some obscure reason almost invariably causes people to lay on flesh.
