Crime and Punishment by Fyodor Dostoyevksy:
The old woman was as always bareheaded. Her thin, light hair, streaked with grey, thickly smeared with grease, was plaited in a rat’s tail and fastened by a broken horn comb which stood out on the nape of her neck. As she was so short, the blow fell on the very top of her skull. She cried out, but very faintly, and suddenly sank all of a heap on the floor, raising her hands to her hand. In one hand she still held “the pledge.” Then he dealt her another and another blow with the blunt side and on the same spot. The blood gushed as from an overturned glass, the body fell back. He stepped back, let it fall, and at once bent over her face; she was dead. Her eyes seemed to be starting out of the sockets, the brow and the whole face were drawn and contorted convulsively.
