"Tom Tyler spied on Creek House, and he found out something. Red Kelso warned him, and Tyler refused to take the warning. Result: his ship was wrecked. We don't know how yet, but we'll find out. Another thing: Mrs. Tyler was frightened, and Tom Tyler is afraid to talk. What's your guess on that?"

Scotty kicked a pebble out of the path. "Kelso again. When Tyler didn't take the first warning, his trawler was wrecked and he was told that next time something would happen to his family. That's the only threat they could make stick with a man like Tyler. If they threatened him, he'd laugh at them. But if they threatened his wife and little girl ..."

"That's the way I see it, too. Now, what kind of business requires a boat, a house on a secluded part of the beach, and a guard with a rifle?"

"Smuggling," Scotty said flatly.

Smuggling. It was the answer that fitted. Rick didn't know yet what kind of smuggling, but he intended to find out. "If you were the Kelsos, and if you were bringing contraband into Creek House, how would you get it out of Seaford?" he asked.

Scotty thought it over. "Not trucks," he said. "Cap'n Mike said he hadn't seen any trucks calling at Creek House. How about taking it somewhere in a small boat?"

In his mind's eye Rick saw the countryside surrounding Creek House as he had seen it from the air. "Right up Salt Creek," he said excitedly. "How about that? If they unloaded at the pier when the Albatross came in and then reloaded into a motor dory or some other kind of small boat, they could take it right up Salt Creek to the bridge. Then all they would need would be a truck waiting there. And if they did it late at night, there wouldn't be any traffic to worry about."

"That must be it!" Scotty exclaimed. Then he sobered. "But how are we going to find out if that's the answer?"

There was only one way. "I guess we're just going to have to see for ourselves," Rick said. As they passed the dry cleaning establishment, he took the bundle of newspaper-wrapped clothes he had been carrying and dropped them into the night-service opening. A whiff of departed menhaden smote his nose forcefully and he added grimly, "Believe me, it'll be a pleasure!"
