No one answered him. Brubaker moved away from us. I glanced down at Ruth's face. Her lips were compressed. She watched the patrolman wade out into the water. It shelved off abruptly. He thrashed and caught his balance, the water up to his chest. He adjusted the face mask, bit down on the mouthpiece. He glanced toward us, then moved forward and was gone, leaving a swirl of turbulence on the surface. The ripples spread out, died away. Prine lit a cigarette, threw the match aside with a quick, impatient gesture. He had looked tall when I had seen him behind his desk. Standing beside me he was not tall at all. His trunk was very long, but his legs were short and heavy. The long minutes passed. We made idle talk, but we kept our voices low. The pines on far hills looked black. The man came abruptly to the surface about forty feet off shore. He swam to the shore and waded out of the water, dripping. He pushed the face mask up onto his forehead. He was shivering. "Man, it's cold down there," he said. We moved toward him. "Well?" Marion demanded. "Here, sir." He handed Marion something. We looked at it as it lay on Marion's hand. It was the dash lighter out of an automobile, corroded and stained. "I came right up from where it is. It's in about fifty feet of water, half on its side. Gray Studebaker. Illinois plates. The number is CT5851. Empty. Rock bottom. It's on a pretty steep slope. I think it can be hauled out all right." "That number checks out," Prine said in a reluctant voice. "Damn it, how can you figure a thing like that?" "Steve," Marion said, "I guess maybe we goofed on this one. I guess maybe that Rose Fulton was right." * * * * * Ruth had gone back to town with Peary in his car. She had seemed subdued, thoughtful. As Peary had credited me with making the guess that led to the discovery of the car, I was in Marion's good graces. I had not told them the second installment of the guess--no longer a guess, actually--that Fitzmartin was the blackmailer. The tow truck had arrived. It stood heading away from the water, brakes locked and wheels blocked. The taut cable stretched down into the water. At dusk they had turned on the big spotlights on the tow truck. About twenty people watched from a place just down the lake shore. Captain Marion had herded them down there out of the way. More men had come out from town. They had been searching the area, prodding into the soft earth with long steel rods. The tired patrolman surfaced again and came to shore. "It ought to do it this time," he said. "I got the hook around the rear axle and fastened back on the cable." He stood in the light. He had scratched his arm on a rock. There was a sheen of water-diluted blood on his forearm. "Try her again," Marion called.
