Elias Kachunga's first half double gave Huddersfield a thoroughly deserved 2-1 win against fellow Sky Bet Championship promotion chasers Norwich.
The striker's early header was cancelled out almost immediately by Jonny Howson but the Terriers quickly recovered their composure and completely dominated the opening period, with Kachunga scoring again four minutes before the break for what proved to be the decider.
The Canaries, who had won their previous two home games without conceding, improved after the break but could find no way back as their stylish opponents saw out the game to make it three straight victories.
