The greatest puzzle is simple enough when you know the answer.
Bowser the Hound.
There were just two people to whom the disappearance of that fat hen Reddy Fox had hidden in the hollow stump was not a mystery. One of them was Blacky the Crow. When the farmer and Bowser the Hound had rushed out at the sound of Blacky's excited cawing, Blacky had flown to the top of a tall tree from which he could see all that went on. Everything had happened just as Blacky had hoped it would. Bowser had taken the trail of Reddy Fox, and Blacky felt sure that sooner or later Reddy would lead him back home to Farmer Brown's.
Blacky was doubly pleased with himself. He was pleased to think that he had found a way of getting Bowser back home, and he was quite as much pleased because he had been smart enough to outwit Reddy Fox. He didn't wish Reddy any harm, and he felt sure that no harm would come to him. He didn't even wish him to lose that dinner Reddy had come so far to get, but he didn't care if Reddy did lose it, if only his plan worked out as he hoped it would.
"I wonder what he'll do with that fat hen," muttered Blacky, as he watched Reddy race away with it thrown over his shoulders. "He can't carry that hen far and keep out of the way of Bowser. I think I'll follow and see what he does with it."
So Blacky followed, and his eyes twinkled when he saw Reddy hide the fat hen in the hollow stump. He knew that no matter how far Bowser might chase Reddy, Reddy would come back for that fat hen, and he was rather glad to think that Reddy would have that good dinner after all.
"No one will ever think to look in that hollow stump," thought Blacky, "and I certainly will not tell any one. Reddy has earned that dinner. Now I think I'll go get something to eat myself."
At that very instant Blacky's sharp eyes caught a glimpse of a gray form with broad wings, and in a perfect panic of fear Blacky began to fly as fast as he knew how for a thick spruce-tree not far away. He plunged in among the branches and hid in the thickest part he could find. With little shivers of fear running all over him, he peeked out and watched that big gray form. On broad wings it sailed over to that hollow stump. Two long legs with great curving claws reached down in, and a moment later that fat hen was disappearing over the tree tops. Blacky sighed with relief.
"It's a lucky thing for me that robber, Mr. Goshawk, saw Reddy hide that fat hen," muttered Blacky. "If he hadn't, he might have caught me, for I didn't see him at all."
