Forrest made no objection to my suggestion, so we started at our slowest pace. I had very little to do, and the ride was one of the most enjoyable I have ever experienced. The salt breath of the sea was in our faces, and the roar of it in our ears. I was quite sorry when on reaching Worthing it became necessary to leave the coast. Inland the roads were absolutely deserted. We did not meet a single person between Worthing and Horsham, and for the first time I realized how easily the Motor Pirate's movements could evade notice. At Horsham we looked in at the police-station, and Forrest made a formal inquiry as to whether anything had been heard of our quarry in the neighbourhood; but, as we expected, without result. We remained there a little time to stretch our legs and to drink a cup of tea, which the officer in charge prepared for us, and on leaving we proceeded at the same steady pace, arriving in Crawley something after four. There we found that the mail had passed through a quarter of an hour before our arrival, and I questioned whether it would be worth our while to remain any longer on the road.

"We may as well make a night of it," said Forrest, in reply to my remark on the subject, so I turned the car in the direction of Brighton again. We bowled along at about fifteen miles an hour, at which rate I reckoned on catching the mail within half an hour. But we were destined to overtake it in a considerably shorter time, for just after passing the third milestone after leaving the village, our path was blocked by the huge van standing in the middle of the road and all across it.

I pulled up at once. Apparently the vehicle was not much damaged, but the door was broken open, while the parcels with which it had been laden were scattered all over the roadway. One horse lay on the roadway perfectly still, the others had disappeared.

The moment we stopped Forrest leaped from the car; I followed his example. The first object which met our eyes was the form of a man. He lay perfectly still, and I thought he was dead, but my companion had sharper eyes. Taking a knife from his pocket, he hacked at cords which bound the man hand and foot.

"More work of the Motor Pirate," remarked Forrest grimly, as I came to his assistance.

The man was not dead, but he had been so roughly gagged that had we arrived ten minutes later he probably would have been beyond human help. In the condition he was, it took us ten minutes working vigorously to restore his respiration; and after that it took the whole of the contents of my pocket flask to restore him sufficiently to enable him to give us an account of the mishap which had befallen him.

Then we learned that the man was the driver of the mail, and that Forrest's surmise that we had happened once more upon the handiwork of the Motor Pirate was correct. He had, it appeared, been driving quietly along, when his attention had been arrested by the curious high-toned hum which presaged the Pirate's approach. He was wondering what the curious noise could be, when he suddenly realized that a long low car was beside him. He did not anticipate any harm either to himself or to his charge, for, though he fancied that the stranger was the noted criminal, he shared the impression, pretty common until then, that the Pirate confined his attentions to motorists. The stranger did not even call upon him to pull up. He ran beside the coach, then slightly increasing his speed, he drew level with the wheelers of the team. There was the sound of a pistol shot, the off wheeler fell dead in his tracks, bringing down the other horses in his fall, and swinging the vehicle right across the road. The driver only escaped being pitched from his seat by the strap which held him to it.

"Then," continued the man, "he ups with 'is pistol an' tells me to come dahn, an' dahn I toddles pretty quick. 'Sorry ter inconwenience yer, my good feller,' ee says. 'Don't menshing it,' I says, as perlite as you'd be with a pistol a pointing at yer 'ed. 'I want the keys er this 'ere waggin,' ee says. 'Sorry they don't trust 'em ter us drivers,' I answers. 'Don't matter worth a cent,' ee says. 'I've another w'y er openin' thet strong box. Put yer 'ands be'ind yer an' turn rahnd,' ee says. I done it, an' ee trusses me up like a bloomin' chicken, an' sticks my own angkincher dahn me froat. With thet ee walks along ter the door and blows the bloomin' locks orf with 'is pistol. That did it. Ee looks inside, an' the w'y ee cleared them parcels aht was a sight—well, yer can see fer yerself wort it's like. The other 'orses were thet mad they kicks theirselves free. Ee goes froo the parcels cool as a cowcumber until ee routs aht the registered parcels. Ee puts them in 'is car. 'Tar, tar!' ee says, wiving 'is 'and, an' orf ee goes jest abaht five minutes afore you gents comed along."

When Forrest realized how near we had been to coming to close quarters with our quarry, he went aside, and for the first time since I had made his acquaintance, I heard him swear. It was a successful effort. He returned to my side the next moment.

"The telegraph is our only chance," he said. "Drive like hell back to Crawley."
