Read it through once

“There’s a letter for you, Mrs. Linton,” I said, gently inserting it in one hand that rested on her knee. “You must read it immediately, because it wants an answer. Shall I break the seal?” “Yes,” she answered, without altering the direction of her eyes. I opened it—it was very short. “Now,” I continued, “read it.” She drew away her hand, and let it fall. I replaced it in her lap, and stood waiting till it should please her to glance down; but that movement was so long delayed that at last I resumed—“Must I read it, ma’am? It is from Mr. Heathcliff.”
