going for walks and spent hours exploring the old temple in a fort nearby. Sometimes they pretended to be rulers of an ancient kingdom. At other times, they played hide-and-seek.

"Catch me if you can," shouted Arun, and he ran ahead.

“I’ll catch you in a minute,” replied Seema, as she followed.

Arun was soon out of sight as he went round the corner. Seema knew his favourite hiding place and smiled to herself thinking. "He won't escape me.

She ran down the hill towards the old temple where she knew Arun would be hiding.But he wasn't there!

He must have gone to the cave,' she thought. This was another favourite place for them -a cave hidden behind some creepers.

"Arun. I'mhere." Seema called out as she reached the cave.

There was no reply. Seema could not see anyone. She was about to enter the cave when she caught sight of a piece of torn,crumpled paper on the ground. She picked it up and unfolded it out. How odd! It hadletters CLP written on it!

Just then she heard Arun calling out, "Seema, where are you?

"Here," said Seema to Arun, who was standing at the entrance of the cave. I was looking for you."

"What have you got in your hand? asked Arun.

It's nothing - just a piece of paper with CLP written on it," said Seema. "Don't throw it. Let me see it," said Arun, as he took the paper from her. He looked at it carefully and said, "See, if you look at the torn edge of the letter, which could be an E and not a C."

"Do you think it could be HELP" asked Seema.

"HELP... My goodness! Someone is in trouble. We must find him," said Arun.
