There is no sign in the beginning that this detestable Lucy is to be heroine. But in Chapter Four Polly disappears and Lucy takes her place and plays her part. The child Polly had a suffering and passionate heart, for all her little air of fastidiousness and inaccessibility. It is the suffering and passionate heart of Polly that beats in Lucy of the Pensionnat. There is only enough of the original Lucy left to sit in judgment on Ginevra Fanshawe and "the Parisienne".
The child Polly had an Imagination. "'Miss Snowe,' said she in a whisper, 'this is a wonderful book ... it tells about distant countries, a long, long way from England, which no traveller can reach without sailing thousands of miles over the sea.... Here is a picture of thousands gathered in a desolate place--a plain spread with sand.... And here are pictures more stranger than that. There is the wonderful Great Wall of China; here is a Chinese lady with a foot littler than mine. There is a wild horse of Tartary; and here--most strange of all--is a land of ice and snow without green fields, woods, or gardens. In this land they found some mammoth bones; there are no mammoths now. You don't know what it was; but I can tell you, because Graham told me. A mighty goblin creature, as high as this room, and as long as the hall; but not a fierce, flesh-eating thing, Graham thinks. He believes if I met one in a forest, it would not kill me, unless I came quite in its way; when it would trample me down amongst the bushes, as I might tread on a grasshopper in a hay-field without knowing it.'"
It is Polly's Imagination that appears again in Lucy's "Creative Impulse". "I with whom that Impulse was the most intractable, the most capricious, the most maddening of masters ... a deity which sometimes, under circumstances apparently propitious, would not speak when questioned, would not hear when appealed to, would not, when sought, be found; but would stand, all cold, all indurated, all granite, a dark Baal with carven lips and blank eyeballs, and breast like the stone face of a tomb; and again, suddenly, at some turn, some sound, some long-trembling sob of the wind, at some rushing past of an unseen stream of electricity, the irrational Demon would awake unsolicited, would stir strangely alive, would rush from its pedestal like a perturbed Dagon, calling to its votary for a sacrifice, whatever the hour--to its victim for some blood or some breath, whatever the circumstances or scene--rousing its priest, treacherously promising vaticination, perhaps filling its temple with a strange hum of oracles, but sure to give half the significance to fateful winds, and grudging to the desperate listener even a miserable remnant--yielding it sordidly, as though each word had been a drop of the deathless ichor of its own dark veins."
