This is the third chapter in The Lost El Dorado series. The Lost Treasure of the Jamaican Pirate, is a treasure hunt for ancient gold set in a Blue Hole in the southern waters of the Caribbean Sea.

The PT boat returns with its usual crew of treasure hunters to find the lost treasure which was placed there by a Jamaican Pirate named Captain Lester Smith in the late 1800's. He had been commissioned by the Union Army to fight against the Confederate Army, but, because of a last-minute swindle, he was forced to flee for his life, taking the Union money and became an outlaw.

Now it is almost 150 years later and his great grandson, also a pirate, named Captain Lester Smith is hot on his ancestor's trail to find the lost treasure. There is a mercenary also looking for the gold and the three groups clash in their quest to find the lost treasure.

The crew of the PT boat led by Captain Bill Treese, are diving in the dangerous water of the Blue Hole, which has held its secrets for the past century. Will they find the gold, only to lose it in the end to the other parties involved, or will they unlock a famous mystery and live to tell about it?

Only time will reveal the lost treasure of the Jamaican pirate!
