+radical chances, putting his king into such sharp and unnecessary perils that it even provoked comment from the 
+white-haired old lady knitting placidly by the fire. "Hark at the wind," said Mr. White, "who, having seen a fatal 
+mistake after it was too late, was amiably desirous of preventing his son from seeing it. I'm listening," said the 
+latter grimly surveying the board as he stretched out his hand. "Check." I should hardly think that he's come 
+tonight," said his father, with his hand poised over the board. "Mate," replied the son. "That's the worst of living 
+so far out," balled Mr. White with sudden and unlooked-for violence; "Of all the beastly, slushy, out of the way 
+places to live in, this is the worst. Path's a bog, and the road's a torrent. I don't know what people are thinking 
+about. I suppose because only two houses in the road are let, they think it doesn't matter." '''
