Flagler Street was still Yuletide-gaudy in the twilight. Its red and green decorations made a gay tent. When he stopped for a traffic light, a newsboy intoned, “No trace of missing Bowl Queen! Read all about it!” He drove on. Down Biscayne Boulevard, across the Causeway.

The inland passage gleamed with lights from big houses and the lights of Christmas trees. Many homes were strung with colored lights and many palms wore crowns of lights.

Boats were tied up at private wharves — speedboats, luxury fishing cruisers, houseboats, yachts. He passed No. 4300, a Spanish residence set back from the street, with a seagoing yacht of its own, brightly lighted trees in its yard and a wall all around.

Duff turned into a side street and went back on foot, furtively. There were no pedestrians. For a moment, as he peered around the ornamental coral entrance posts at the big house, Duff had a feeling of hopelessness. The estate looked civilized, secure, and so remote from what tormented him that Duff considered turning back. Then, in the first real confirmation of his frantic weeks, he saw it: a little square of whiteness, of almost luminous whiteness, in the shadow. He made as sure as he could that he was not seen, crossed the drive and picked up a woman’s folded handkerchief, not dropped on the walk, but tossed, it seemed, toward the entrance post. His fingers shook as he saw the initials: E. Y.

He found a rubber tree that overhung the wall and, after a look in each direction, disappeared in its foliage. He dropped onto the lawn. Moving from bush to bush, he reached the big house.

The lawn lights intensified the shadows. As long as he didn’t expose himself to the red, green, blue and yellow shimmer, they would dazzle anyone looking out of the windows.

Duff moved along the wall behind thick crotons.

There were four men in the library, drinking cocktails. Dinner guests, Duff imagined.

No women. There were three or four servants in the kitchen and pantries; they, also, were men. At the back of the house, a concrete driveway and a paving-stone walk led to the dock where the yacht was moored. Two decks, about eighty feet long. A motor was running somewhere aboard her; she showed lights.

Duff barely managed to hide himself in time when a rear door opened and a man carried a carton of supplies to the ship. The man wore a white coat and Duff heard him speak to someone on board.
