"Well, we have to be satisfied, I suppose," replied Frank, leaning farther over the handlebars. "Perhaps dad may give us a chance on a real case some time."

"Some time! I want to be on a real case now!"

The motorcycles roared along the narrow road that skirted the bay. An embankment of tumbled rocks and boulders sloped steeply to the water below, and on the other side of the road was a steep cliff. The roadway itself was narrow, although it was wide enough to permit two cars to meet and pass, and it wound about in frequent curves and turnings. It was a road that was not often traveled, for Willowville was only a small village and this shore road was an offshoot of the main highways to the north and the west.

The Hardy boys dropped their discussion of the probability that some day they would become detectives, and for a while they rode on in silence, occupied with the difficulties of keeping to the road. For the road at this point was dangerous, very rough and rutty, and it sloped sharply upward so that the embankment leading to the ocean far below became steeper and steeper.

"I shouldn't want to go over the edge around here," remarked Frank, as he glanced down the rugged slope.

"It's a hundred-foot drop. You'd be smashed to pieces before you ever hit the shore."

"I'll say! It's best to stay in close to the cliff. These curves are bad medicine."

The motorcycles took the next curve neatly, and then the boys confronted a long, steep slope. The rocky cliffs frowned on one side, and the embankment jutted far down to the tumbling waves below, so that the road was a mere ribbon before them.

"Once we get to the top of the hill we'll be all right. It's all smooth sailing from there to Willowville," remarked Frank, as the motorcycles commenced the climb.

Just then, above the sharp put-put of their own motors, they heard the high humming roar of an automobile approaching at great speed. The car was not yet in sight, but there was no mistaking the fact that it was coursing along with the cut-out open and with no regard for the speed laws.
