Four minutes later—four miles up the smoke-shrouded river, with Midtown Manhattan on his right and the Weehawken piers thrusting into the water on his left—a high-power rifle slug whistled past his head.

ANOTHER SLUG CRACKLED BY. A third slammed through the Eagle’s fuselage immediately behind Isaac Bell and shook the back of his seat. A fourth screeched off the tip of the triangular steel king post above the wing. Heavy bullets—Marlin .45-70s, Bell guessed—Frost’s favorite. A fifth shot banged his rudder so hard, it rattled the control post. The gunfire was coming from behind him now. He had overflown Frost’s position and was moving out of range.

Bell spun the American Eagle on a dime and roared back, searching the busy river for the boat from which the gunman had fired. He had been flying up the middle of the mile-wide Hudson when the shooting started, equidistant between the pier-lined shores of Manhattan Island and New Jersey. The resultant half-mile range was too far from land for Frost to have done such accurate shooting. He was directly under Bell, somewhere in the gloom of smoke and haze, screened by the moving traffic of tugs, barges, car floats, lighters, ferries, launches, and sailing vessels.

Bell spotted a short, wide, flat gray hull scooting between a triple-track car float carrying half a freight train, and a three-masted schooner under clouds of sail. He descended to investigate. It was an oyster scow moving at an unusual rate of speed, trailing a long white wake and blue exhaust from a straining gasoline engine. The helmsman was hunched over his tiller in the stern. Its mast had been unstepped and shipped flat on the deck. A passenger was sprawled on his back beside the mast. He was a big man, Harry Frost’s size, who appeared to have fallen. But as Bell’s aeroplane caught up with the scow, he saw the sun glint on a long rifle.

Bell grabbed the control wheel in his left hand, drew his pistol with his right, and shoved the control post forward. If Harry Frost wondered why his wife’s yellow monoplane had circled back, he was about to get the surprise of his life when he learned that he had mistaken a similar profile in an identical color for Josephine’s Celere.

The Eagle dove at the oyster scow. Bell braced the automatic on the hull of the aeroplane, found the supine figure in his sights, and pulled the trigger three times. He saw one of his shots send wood chips flying from the deck and another tear a long furrow in the mast. The aeroplane lurched on an air current, and his third shot went wild.
