A message for the Inca king

It was before dawn when Poma heard a voice. “Wake up, Poma!” somebody whispered. Poma opened his eyes. He saw the face of his old teacher. Poma sat up in surprise.

“Sh!” said his teacher. “Don't speak. Get dressed and follow me.”

Hurriedly, Poma put on his tunic. The other boys were sleeping.

As silent as shadows they crossed the courtyard and entered the great hall. Poma's teacher led him towards a small doorway in one corner. Messengers did not usually go through it. The rooms behind the hall were part of the palace. Suddenly the old man stopped and spoke.

“Listen, Poma,” he said. “You are the youngest messenger in the palace but nobody runs as fast as you. You are not yet seventeen but you are as brave as any man. Now you have an important task. Come.”

Poma followed the old man through the narrow doorway. They entered a large room where lamps burned brightly. A table stood in the middle of the room with a gold chair next to it. There were silver cups on the table but the chair was empty. Poma's teacher said, “This is the boy, Prince Urco”

A tall man appeared from the shadows. Bands of gold circled his head and his arms. He beckoned to Poma and the boy stepped forward.

The prince looked carefully at Poma for a moment. “You are strong,” he said, “but you must be clever, too. You must take a message to the king. You must remember every word.” He leaned forward and spoke clearly. “Repeat,” he commanded. Poma repeated the message. “Now go,” he said, “and do not fail.”

Poma left the room and ran back through the hall. Then he ran straight on, out of the city gates and towards the forest. “I must not fail,” he repeated.
