"No," replied Gunn. "It's our habit to lower the chamber before dawn so it'll be in place and ready to receive the divers in case of an early morning emergency."

"There's your answer!" Pitt exclaimed. "Someone swam under cover of the pre-dawn darkness to the cable and set off the Primacord. Visibility may be one hundred feet after the sun comes up but at night it's less than one foot."

"And the noise from the blast?"

"Elementary my dear Gunn." Pitt grinned. "I should guess that a small amount of Primacord detonating at approximately eighty feet of depth would sound very similar to a sonic boom from one of Brady Field's F-105 Starfires."

Gunn looked at Pitt with respect. It was basically a sound theory, and obviously there was little he could think of to debate about. His forehead creased. "Where do we go from here?"

Pitt downed the scotch and banged the glass onto Gunn's desk. "You just stay in the briny and fish for your Teaser. I'm going back to the island and try my hand at a little hunting. There may be a tie-in with your disruptions and the attack on Brady yesterday, and the next step will be to find who's behind this mess and what their motives are."

Suddenly the door burst open and a man leaped into the cabin. He wore only a pair of abbreviated swim trunks and a wide belt, containing a knife and a nylon net bag. His wet, sun-bleached hair was streaked with whitish yellow and freckles dotted his nose and chest. As he stood there, the water dripped to the carpet around his feet in spreading dark stains. "Commander Gunn," he shouted excitedly. "I've seen one! I've actually seen a Teaser, not more than ten feet in front of my mask."

Gunn jumped to his feet. "Are you sure? Did you get a close look at him?"

"Better than that, sir, I took a picture of him."

The freckle-nosed man stood there, grinning with every available tooth. "If only I had a speargun, I might have got him, but I was shooting coral formations with my camera instead."

"Quick," snapped Gunn. "Get that film to the lab and have it developed."

"Yes sir." The fellow turned and dashed out of the door, spraying Pitt with a few drops of salt water as he passed.

Gunn's face had a happy but determined look. "My God. To think I was about to give up, throw my tail between my legs and set a course for home. Now, dammit, I'm going to stay anchored here until I die of old age or catch a Teaser." His eyes twinkled as he glanced at Pitt. "Well, Major, what do you think of that?"

Pitt merely shrugged. "Personally, I perfer angling for girls." With very little effort his mind dropped the business at hand and formed a tantalizing picture of Teri standing on the beach in her red bikini.
