"Yes, I see him," replied Alec, gently retarding the terrific momentum. "'Fraid he's spoiled my record."

"Motor-cyclist," corrected Jack, as the approaching machine breasted one of the intervening ridges and disappeared in a dip of the road. "Wonder if anything would happen if a bike going at, say, forty, passed a big car doing seventy? If——"

He broke off. Simultaneously Claverhouse throttled down and applied the side-brakes.

Before the car could be brought to a standstill it had surmounted a slight rise and was on the down grade leading to another ascent half a mile or more away. Right in the hollow was a confused group of figures which resolved itself into a motor-cyclist bravely defending himself against four rough-looking men. The cycle lay on the grass a good ten yards from the road and a fifth ruffian was already beginning to ransack the contents of a case strapped to the carrier.

At first sight Villiers thought that there had been an accident, and that the motor-cyclist had collided with a group of pedestrians, but he was speedily undeceived. It was a case of highway robbery.

Unfortunately, from the footpads' point of view, the rascals had not bargained for the approach of a car at seventy miles an hour. Lying in wait for the solitary traveller, they had taken the precaution to see that the straight road was otherwise deserted when the object of their attention approached. Nor were they aware of the presence of the swift, silent car until it appeared to leap from the ground within a hundred yards of them.

"Look out, chums!" shouted the fellow standing over the fallen motor-cycle, and acting upon his own warning he promptly took to his heels.

The others also fled, but not before one of them was held by the attacked motor-cyclist. It looked as if the fellow would be made a prisoner, for the other held on like a leech, until the ruffian drew a knife and struck.

"After them!" yelled Beverley, taking a flying leap from the car. Villiers was a close second, ignoring Claverhouse's suggestion to take the car in pursuit.

As it was the chase was futile. The assailants, young, agile, and strong in wind, scattered in different directions, steadily outdistancing the three new arrivals, hampered as they were with heavy coats.
