Phil Brent was plodding through the snow in the direction of the house where he lived with his step-mother and her son, when a snow-ball, moist and hard, struck him just below his ear with stinging emphasis. The pain was considerable, and Phil's anger rose. He turned suddenly, his eyes flashing fiercely, intent upon discovering who had committed this outrage, for he had no doubt that it was intentional.
