He spent a few hours at the Casino, then sauntered out into the town. Presently he reentered the car and drove off in the direction of Mentone. Earlier in the afternoon he had noticed an inconspicuous grey car some little distance behind him. He noticed it again now. He smiled to himself. The road was climbing steadily upwards. The Comte’s foot pressed hard on the accelerator. The little red car had been specially built to the Comte’s design, and had a far more powerful engine than would have been suspected from its appearance. It shot ahead.

Presently he looked back and smiled; the grey car was following behind. Smothered in dust, the little red car leaped along the road. It was travelling now at a dangerous pace, but the Comte was a first-class driver. Now they were going downhill, twisting and curving unceasingly. Presently the car slackened speed, and finally came to a standstill before a Bureau de Poste. The Comte jumped out, lifted the lid of the tool chest, extracted the small brown paper parcel and hurried into the post office. Two minutes later he was driving once more in the direction of Mentone. When the grey car arrived there, the Comte was drinking English five o’clock tea on the terrace of one of the hotels.
