A GREAT MURDER MYSTERY! There may be folk in the world to whom the finding of a dead man, lying grim and stark by the roadside, with the blood freshly run from it and making ugly patches of crimson on the grass and the gravel, would be an ordinary thing; but to me that had never seen blood let in violence, except in such matters as a bout of fisticuffs at school, it was the biggest thing that had ever happened, and I stood staring down at the white face as if I should never look at anything else as long as I lived.
