It was a deserted bit of coast. But any one who had been standing near the promontory the next day might have seen a thin line as if the water, sparkling in the sunlight, had been cut by a huge knife. Gradually a thin steel rod seemed to rise from the water itself, still moving ahead, though slowly now as it pushed its way above the surface. After it came a round cylinder of steel, studded with bolts. It was the hatch of a submarine and the rod was the periscope.
As the submarine lay there at rest, the waves almost breaking over it, the hatch slowly opened and a hand appeared groping for a hold. Then appeared a face with a tangle of curly black hair and keen forceful eyes. After it the body of a man rose out of the hatch, a tall, slender, striking person. He reached down into the hold of the boat and drew forth a life preserver.
"All right," he called down in an accent slightly foreign, as he buckled on the belt. "I shall communicate with you as soon as I have something to report."
Then he deliberately plunged overboard and struck out for the shore. Hand over hand, he churned his way through the water toward the beach until at last his feet touched bottom and he waded out, shaking the water from himself like a huge animal.
The coming of the stranger had not been entirely unheralded. Along the shore road by which Kennedy and I had followed the crooks whom we thought had the torpedo, on that last chase, was waiting now a powerful limousine with its motor purring. A chauffeur was sitting at the wheel and inside, at the door, sat a man peering out along the road to the beach. Suddenly the man in the machine signalled to the driver.
"He comes," he cried eagerly. "Drive down the road, closer, and meet him."
The chauffeur shot his car ahead. As the swimmer strode shivering up the roadway, the car approached him. The assistant swung open the door and ran forward with a thick, warm coat and hat.
Neither the master nor the servant spoke as they met, but the man wrapped the coat about him, hurried into the car, the driver turned and quickly they sped toward the city.
Secret though the entrance of the stranger had been planned, however, it was not unobserved.
Along the beach, on a boulder, gazing thoughtfully out to sea and smoking an old briar pipe sat a bent fisherman clad in an oilskin coat and hat and heavy, ungainly boots. About his neck was a long woolen muffler which concealed the lower part of his face quite as effectually as his scraggly, grizzled whiskers.
