"Above the wide stone fireplace was a large old gold mirror, a mirror that took into its expanse the whole of the room, so that, standing before it, with your back to the door, you could see everything that happened behind you. The mirror was old, and gave to the view that it embraced some comfortable touch, so that everything within it was soft and still and at rest." Henry Trenchard, gazing into it, saw "the reflection of the room, the green walls, the green carpet, the old faded green place, like moss covering dead ground. Soft, dark, damp.... The people, his family, his many, many relations, his world, he thought, were all inside the mirror--all imbedded in that green, soft, silent inclosure. He saw, stretching from one end of England to the other, in all provincial towns, in neat little houses with neat little gardens, in cathedral cities with their sequestered closes, in villages with the deep green lanes leading up to the rectory gardens, in old country places by the sea, all these people happily, peacefully sunk up to their very necks in the green moss.... His own family passed before him. His grandfather, his great-aunt Sarah, his mother and his father, Aunt Aggie and Aunt Betty, Uncle Tim, Millicent, Katherine." Katherine embodied the spirit of revolt from the tyranny of family. When Philip Mark, a young Englishman, who has spent the greater part of his life in Russia, and whose experiences have made him more Russian than English, comes wooing in tempestuous fashion, she throws off the yoke of her family and chooses for herself. It is when the ties of family are about to be shattered that Henry Trenchard, in a fit of passion, flings a book at Mark, the invader, who has shaken Katherine’s faith in the family, and, instead of hitting Mark, demolishes the mirror. "There was a tinkle of falling glass, and instantly the whole room seemed to tumble into pieces, the old walls, the old prints and water colors, the green carpet, the solemn bookcases, the large armchairs--and with the room the house, Westminster, Garth, Glebeshire, Trenchard and Trenchard traditions--all represented now by splinters and fragments of glass." "_The Green Mirror_, the second in the series of the _Rising City_ series, which was opened by _The Duchess of Wrexe_, is not only quite individual in style but the story is told with a most vivid sense of that which the realists are supposed to lack--form. But there is no sacrifice of truth to it. The psychology of the characters rings true. The reaction of an unimaginative, sober, righteous family to a prospective son-in-law has seldom been better done. The story will add to Mr. Walpole’s reputation and will not at all suffer from the fact that it was written before the war, as his overmodest preface might indicate that he fears."--_Chicago Evening Post_.
