It was a tricky entrance. The current was pushing him to port. He thought that Odysseus and his crews must have found entering the harbor duck soup for mariners who had crossed the Atlantic Ocean. Their advantage in navigating unruly waters was that they could throw out their oars and row. Dirk could have started the engine, but like a pilot with an aircraft that could land by autopilot, he preferred to use his own skills and take her in himself.

Once through the straits, the water calmed and he watched the bottom slowly pass under the keel. He turned the wheel back over to Summer and dropped the sails. Then he started the little diesel and began inspecting the interior of the harbor.

It was small, no more than half a mile in length and half again as much in width. While Summer leaned over the side and inspected the bottom for any unusual anomalies, he leisurely cruised back and forth across the harbor, trying to get a feel for the current and imagining himself on the deck of one of Odysseus' ships, trying to predict where the ancient mariners might have anchored so many centuries ago.

Finally, he settled in an area that was sheltered from the prevailing winds by a rise on the island, a sandy mound that rose nearly a hundred feet above the shoreline. He shut off the engine and dropped the bow anchor by flicking a switch in the cockpit that lowered it by a winch.

"This looks about as good a place as any to go over the side and inspect the bottom."

"It looks flat as a dining room floor," said Summer. "I saw no humps or contours. It stands to reason that wood from a Celtic shipwreck would have rotted away thousands of years ago. Any pieces that survived have to be buried."

"Let's dive. I'll test the consistency of the sand and silt. You swim around and do a visual inspection."

After they put on their dive gear, Dirk checked the anchor to be sure it was snug on the bottom and wouldn't break loose and allow the boat to drift away. Not that it would go far in the harbor. Without the need for wet suits to protect their bodies from cold water temperatures or sharp coral, they went over the side in ten feet of water in only their bathing suits. The water was almost as clear as glass. Visibility was nearly two hundred feet, the temperature warm in the middle eighties, perfect diving conditions.

Forty minutes later, Dirk climbed up the boarding ladder to the deck and removed his air tank and weight belt. He had run a metal probe beneath the surface of the sand, checking for a harder clay layer beneath but found fifteen feet of soft sand before striking bedrock. He sat there for a few minutes, watching Summer's air bubbles travel around the boat. Soon, she was climbing aboard and paused on the boarding ladder to carefully set a coral-encrusted object on the deck. Then she stood with water trickling down her body onto the teak deck as she slipped out of her dive gear.

"What have you got?" asked Dirk.

"I don't know, but it feels too heavy for a rock. I found it a hundred yards offshore, protruding out of the sand."

Dirk sca

He picked up the object and gently chipped away the encrustation with his dive knife. Soon the object took on the look of a bird with outstretched wings.

"Looks like an eagle or swan," he said. Then the tip of his knife cut a small scratch that showed silver. "The reason it's heavy is because it's cast out of lead."

Summer took it in her hands and stared at the wings and the beaked head that was turned to the right. "Could it be ancient Celt?"

"The fact that it's sculpted out of lead is a good sign. Dr. Chisholm told me that, besides tin, one of the main attractions of Cornwall was its lead mines. Did you mark the site where you found it?"

She nodded. "I left my probe in the sand with a little orange flag on it."

"How far out?"

"About fifty feet in that direction," she said, pointing.

"Okay, before we dredge or probe with the water jet, we'll run over your site with the metal detector. The side-scan sonar won't be of much use if all the ship wreckage is buried."

"Maybe we should have had Rudi send a magnetometer."

Dirk smiled. "A magnetometer detects the magnetic field of iron or steel. Odysseus sailed long before the Iron Age appeared. A metal detector will read iron besides most other metals, including gold and bronze."





Summer turned on the Fisher Pulse 10 detector as Dirk co

"Ready?" he asked.

"All set," answered Summer.

Turning over the diesel engine, Dirk began making closely spaced survey lines over the target area, mowing the lawn until they struck an anomaly. After only fifteen minutes, the needle on the meter began to zig and zag in unison with an increased buzzing sound over Summer's earphones.

"We're coming up on something," she a

Then came a slight zip in sound and a brief swing of the needle as they passed over Summer's metal probe that was sticking out of the bottom.

"Get a good reading?" asked Dirk.

Summer was about to answer in the negative when the needle began wildly sweeping back and forth, indicating a metallic object or objects passing under the keel. "We have a pretty good mass down there. What direction are we ru

"East to west," replied Dirk, marking the target coordinates from his global positioning instrument.

"Run over the site again, but this time from north to south."

Dirk did as he was told, passing beyond the target for a hundred yards before swinging Dear Heart on a ninety-degree turn heading north to south. Again the meter and audio sound went wild. Summer penciled the meter readings in a notebook and looked up at Dirk standing at the wheel.

"The target is linear, about fifty feet in length with a broad dipolar signature. It looks to have a minimal but dispersed mass, similar to what you'd expect from a broken-up sailing vessel."

"It seems to be in the expected range of an old wreck. We'd better check it out."

"How deep is the water?"

"Only ten feet."

Dirk eased the boat around again, shut down the engine and let the Dear Heart drift with the current. When the GPS numbers began to match those of the anomaly, he dropped the anchor. Then he fired up the compressor.

They put on their dive gear and dropped into the water from opposite sides of the boat. Dirk turned the valve for the water jet and pushed it into the sand in the ma

"Something down there, all right," he said, spitting out his mouthpiece as they surfaced. "About the right size for an ancient ship."

"Could be anything," said Summer sensibly, "from the wreck of an old fishing boat to trash dumped off a barge."

"We'll know as soon as we dig a hole with the induction dredge."

They swam back to the boat, attached the hose to the dredge and dropped it into the water. Dirk volunteered for the dirty job of excavation while Summer stayed aboard to watch the compressor.
