Mr. Briggerland did not enthuse over any form of sport or exercise. His hobbies were confined to the handsome motor-cycle, which not only provided him with recreation, but had, on occasion, been of assistance in the carrying out of important plans, formulated by his daughter.

He stopped at Mentone for breakfast and climbed the hill to Grimaldi after passing the frontier station at Pont St. Louis. He had all the morning before him, and there was no great hurry. At Ventimille he had a second breakfast, for the morning was keen and his appetite was good. He loafed through the little town, with a cigar between his teeth, bought some curios at a shop and continued his leisurely journey.

His objective was San Remo. There was a train at one o'clock which would bring him and his machine back to Monte Carlo, where it was his intention to spend the remainder of the afternoon. At Pont St. Louis he had had a talk with the Customs Officer.

"No, m'sieur, there are very few travellers on the road in the morning," said the official. "It is not until late in the afternoon that the traffic begins. Times have changed on the Riviera, and so many people go to Cannes. The old road is almost now deserted."

At eleven o'clock Mr. Briggerland came to a certain part of the road and found a hiding-place for his motor-cycle--a small plantation of olive trees on the hill side. Incidentally it was an admirable resting place, for from here he commanded an extensive view of the western road.

Lydia's journey had been no less enjoyable. She, too, had stopped at Mentone to explore the town, and had left Pont St. Louis an hour after Mr. Briggerland had passed.

The road to San Remo runs under the shadow of steep hills through a bleak stretch of country from which even the industrious peasantry of northern Italy cannot win a livelihood. Save for isolated patches of cultivated land, the hills are bare and menacing.

With these gaunt plateaux on one side and the rock-strewn seashore on the other, there was little to hold the eye save an occasional glimpse of the Italian town in the far distance. There was a wild uncouthness about the scenery which awed the girl. Sometimes the car would be running so near the sea level that the spray of the waves hit the windows; sometimes it would climb over an out-jutting headland and she would look down upon a bouldered beach a hundred feet below.

It was on the crest of a headland that the car stopped.

Here the road ran out in a semi-circle so that from where she sat she could not see its continuation either before or behind. Ahead ............
