Four of them. All werewolves. One was in full wolf form, lying on the ground, panting. His muzzle was red with blood, and one of his forefeet had been sliced clean off. The others were on two legs but in little better condition: bloodied and slashed, wounded repeatedly with horribly sharp blades. Hermione smelled blood, sweat, dirty fur, and urine, but none of the smoke or stinging scents of magic.
