Jack made no movement. He knew from his life on the farm that animals and birds are afraid of sudden quick movements, even from a friend. His heart beat loudly, for he was not at all sure that one or both of the dogs might not attack him.

Don barked again. Tinker ran up to Jack and sniffed at him. Jack sat perfectly still. The dog smelt the meat sandwiches and the biscuits and tried to get his nose in the bag. Both dogs were underfed, because Mr. Diaz thought they would be wide awake then, if they were hungry, and would not sleep well as a properly fed dog does.

“Good dog, Tinker, good dog,” said Jack in a very low voice. The dog sniffed hungrily at the bag. Jack slowly and cautiously undid it. Don, the other dog, would not come near. He stood at a distance, very suspicious, growling softly.

“Growl all you like!” thought Jack. “But don’t start that dreadful barking again. I don’t want Mr. Diaz out here looking round!”

Tinker took a ham sandwich from Jack’s hand. It was gone at a gulp, for the dog was very hungry indeed. He sniffed for another.

Jack slowly put out his hand to the dog’s head and patted it gently. The dog was not used to being kindly treated and was surprised. He gave Jack’s hand a quick lick.

“We’re getting on!” thought the boy. He gave Tinker another sandwich, and that was swallowed at once. Don smelt the meat from where he stood. He decided that if Tinker was friendly to this strange boy, he could be too - and also he badly wanted that nice-smelling meat.

So he ran up, still growling softly. But Jack knew it was a pretend-growl, and he chuckled to himself. He gave the hungry animal a sandwich, and then another. The dog swallowed them both. There were only two more left, so Jack gave the dogs one each.

Then he stood up and took a few cautious steps towards the tower. The dogs did not seem to mind. They could now smell Jack’s biscuits and they kept close to the boy as he walked. Tinker was very friendly indeed, and licked Jack’s hand when he found it near his nose. Don would not do that, but he no longer growled.

Jack walked to the foot of the tower and looked up. He gave each dog a biscuit, and wondered if by any chance the door at the foot of the tower was unlocked. If it was, dare he run up the winding stairway and try to talk to the prisoner? Maybe he could even unlock the door and get the boy out? But no - the dogs would not know Prince Paul and might bark and then they would both be caught.
