impse of Lenox Avenue, which
runs parallel with Fifth, and then they were bowling along St. Nicholas
Avenue. After a half-mile or less, they crossed Eighth Avenue at an
acute angle, but the gray car kept steadily on, and soon was skirting
St. Nicholas Park.

Thenceforth another mile and a half counted as little until the flying
automobile gained the Harlem River Speedway. Here the pace improved.
There was practically no traffic to interfere with progress now, and
Brodie had to maintain an equable rate of forty miles an hour in order
to keep within sight of his quarry.

At last, by way of Nagle and Amsterdam Avenues, they regained Broadway
itself, at the point where its many sinuosities end at the bridges over
the Harlem River and Spuyten Creek.

By this time, McCulloch was undeniably anxious. Many a mile separated
him from the busy activities of Madison Square and its surroundings,
and the main roads of the State of New York were opening up their
possibilities. Still, he was of Scotch-Irish stock, and even the most
ardent Nationalist would be slow to maintain that the men from beyond
the Boyne are what is popularly and tersely described as "quitters."

"I'd be better pleased if I had any sort of notion where that joker was
heading for," he said, with a grim smile. "I didn't count on taking a
joy-ride at this hour of the morning."

That was his sole concession to outraged official decorum. He accepted
a cigar, and forthwith resigned himself to the exigencies of the chase,
which lay not with him but with the dark and devious purposes of the
sinister Anatole.

The end, however, was nearer than any of them was now inclined to
imagine. A rapid run along the main road through Yonkers brought them
to Hastings and the bank of the Hudson River. The comparatively level
grades of New York were replaced by hilly ground, and if they would
avoid courting observation beyond any doubt of error it was essential
that the gray car should be allowed greater latitude. In fact, it was
almost demonstrable that an alert criminal like the man they were
pursuing--if he really were the ally of Hunter's slayers--could hardly
have failed to realize much earlier that he was being followed.
Moreover, being an expert motorist, he would know that the car in the
rear could not only hold him in the race but close up with him whenever
its occupants were so minded. He would not be lulled into false
security by the present widening of the g
