I will tell you.
"When I peered through the door of the cave I saw this: on the floor of the cave lay a she-wolf panting, as though she had galloped many a mile; she was great and fierce.

Near to her was another wolf--he was a dog--old and black, bigger than any I have seen, a very father of wolves, and all his head and flanks were streaked with grey.

But this wolf was on his feet.

As I watched he drew back nearly to the mouth of the cave, then of a sudden he ran forward and bounded high into the air towards the withered foot of that which hung from the cleft of the rock.
His pads struck upon the rock here where it is smooth, and there for a second he seemed to cling, while his great jaws closed with a clash but a spear's breadth beneath the dead man's foot.

Then he fell back with a howl of rage, and drew slowly down the cave.
