During the second week following Chester Greene’s death the weather moderated markedly. We had several beautiful clear days, crisp, sunshiny, and invigorating. The snow had almost entirely disappeared, and the ground was firm, without any of the slush that usually follows a winter thaw. On Thursday Vance and I called at the Greene mansion earlier than on any previous visit, and we saw Doctor Von Blon’s car parked before the gate.
“Ah!” Vance observed. “I do hope the family Paracelsus is not departing immediately. The man lures me; and his exact relationship to the Greene family irks my curiosity.”
Von Blon, as a matter of fact, was preparing to go as we entered the hallway. Sibella and Ada, bundled in their furs, stood just behind him; and it was evident that they were accompanying him.
“It was such a pleasant day,” explained Von Blon, somewhat disconcertedly, “I thought I’d take the girls for a drive.”
“And you and Mr. Van Dine must come with us,” chimed in Sibella, smiling hospitably at Vance. “If the doctor’s temperamental driving affects your heart action, I promise to take the wheel myself. I’m really an expert chauffeur.”
I surprised a look of displeasure on Von Blon’s face; but Vance accepted the invitation without demur; and in a few moments we were riding across town, comfortably installed in the doctor’s big Daimler, with Sibella in front, next to the driver’s seat, and Ada between Vance and me in the tonneau.
We went north on Fifth Avenue, entered Central Park, and, emerging at the 72d Street entrance, headed for Riverside Drive. The Hudson River lay like a sheet of blue-grass below us, and the Jersey palisades in the still clear air of early afternoon were as plainly etched as a Degas drawing. At Dyckman Street we went up Broadway, and turned west on the Spuyten Duyvil Road to Palisade Avenue overlooking the old wooded estates along the water. We passed through a private roadway lined with hedges, turned inland again to Sycamore Avenue, and came out on the Riverdale Road. We drove through Yonkers, up North Broadway into Hastings, and then skirted the Longue Vue Hill. Beyond Dobbs Ferry we entered the Hudson Road, and at Ardsley again turned west beside the Country Club golf-links, and came out on the river level. Beyond the Ardsley Station a narrow dirt road ran up the hill along the water; and, instead of following the main highway to the east, we continued up this little-used road, emerging on a kind of plateau of wild pasture-land.
A mile or so farther on—about midway between Ardsley and Tarrytown—a small dun hill, like a boulder, loomed directly in our path. When we came to the foot of it, the road swung sharply to the west along a curved promontory. The turn was narrow and dangerous, with the steep upward slope of the hill on one side and the precipitous, rocky descent into the river on the other. A flimsy wooden fence had been built along the edge of the drop, though what possible protection it could be to a reckless or even careless driver I could not see.
As we came to the outermost arc of the little detour Von Blon brought the car to a stop, the front wheels pointing directly toward the precipice. A magnificent vista stretched before us. We could look up and down the Hudson for miles. And there was a sense of isolation about the spot, for the hill behind us completely shut off the country inland.
We sat for several moments taking in the unusual view. Then Sibella spoke. Her voice was whimsical, but a curious note of defiance informed it.
