“No time to write much, but they tortured and imprisoned me. A slave got me out of the temple, and took me to the ship, Catamaran, Captain Koosh. They are all pirates.

“My life is in danger every day. I am a prisoner on the pirate ship.

“You will wonder how I send this letter.

“I had concealed my diamond ring. An Arab who waited on me was going to Mecca. I bribed him with the ring to see that you had my letter. Take a ship and come after me. The pirates will kill me soon if I don’t pay the sum they demand for ransom, and you know my obstinate disposition.

“Come to me. You, Mole, Monday and my dear wife, Clara. We are not far up the coast.

“Look out for the Catamaran, Captain Koosh, Pirate ship.”

Harry read the letter aloud.

Mole and Monday were deeply impressed.

The mystery was solved now.

“Well,” exclaimed Harry Girdwood, “we shall have to do as we are told. Jack is the leader, and we will have to follow him.”
