Springing ashore, Dorothy dragged the anchor up the beach and buried it at its full length of rope in the sand. Then with a sigh of satisfaction, she straightened her back and took a survey of her surroundings.
The little beach ran up to a cup-shaped hollow, encompassed by high sand dunes. She had noticed the inlet on the large-scale chart, and chose it because she figured that it lay about a mile on the near side of the cottage she sought. And since she had decided to use the motor boat instead of the plane because she wanted to cover her approach, this spot seemed made to order for her purpose.
Her eyes scanned the skyline, and for a moment her heart almost stopped. Surely she had seen the head of a man move in that clump of long, coarse grasses at the top of the incline! Standing perfectly still, although her body tingled with excitement, she continued to stare at the suspicious clump.
Then with characteristic decision, she drew a revolver from her pocket and raced up the side of the dune. But although she exerted herself to the utmost, her progress was much too slow. Her feet sank deep in the shifting sand until she was literally wading, clawing with her free hand for holds on the waving sandgrass.
Panting and floundering, she pulled herself to the top, only to find no one there. Nor so far as she could see was there any living thing in sight. The deep boom of the surf was louder here, and peering through the rain, she made out the long stretch of beach pounded by combers, not more than a couple of hundred yards away. Some distance to the right, facing the ocean twinkled the lights of a row of summer cottages. To her left nothing could be seen but tier after tier of grass-topped dunes, a narrow barrier of sand between Great South Bay and the Atlantic Ocean, bleak and desolate, extending farther than the eye could reach.
Despite this evidence to the contrary, Dorothy still retained the impression that she was not alone. She had an uneasy conviction that she was being watched. She shivered.
“My nerves must be going fuzzy,” she thought disgustedly. “I can’t risk using a flash, and if there were any tracks this stiff breeze from the sea would have filled them in while I was climbing up here. Well, get going, Dorothy, my girl—this place is giving you the creeps—good and plenty.”
The Colt was slipped back into her slicker, and she trudged through the loose sand to the black stretch of ocean beach. Here, walking was better, and turning her back on the lighted cottages, she set out along the hard shingle by the surf.
Several times during that walk, Dorothy stopped short and scanned the long line of dunes above her. Try as she might, it seemed impossible to rid herself of the idea that someone was following. When she judged the remaining distance to the cottage to be about a quarter of a mile, she left the beach and continued her way over the dunes.
Although Dorothy had no tangible fact to connect the Mystery Plane with her holdup in New Canaan and Terry’s disappearance, she approached the lonely cottage with the stealth of a red Indian. And even if this night reconnoiter should prove only that the bearded aviator had a sweetie living on the shore of Great South Bay, or that he was making daily trips to visit friends, she had no intention of being caught snooping. No matter what she should learn of the cottage’s inmates, if anything, she proposed to return with the Mary Jane to Yancy’s wharf and spend the rest of the night aboard. She had no desire to tramp about Babylon after midnight, looking for a hotel that would take her in.
