Amberley smiled, but for once in his life forbore to retort caustically. His attention was all for the tricky road he was following; the sergeant got monosyllabic answers to his questions and wisely gave up all attempt at conversation.
The trail was a difficult one, often lost. The Vauxhall had left the main roads for a network of country lanes. From time to time Amberley stopped to ask whether it had been seen. Mostly a stolid headshake answered the question, but twice he got news of the car; once from a railway officiall in charge of a level-crossing, once from a night watchman huddled over a brazier in a wooden hut beside some road repairs. The Vauxhall seemed to be heading south-west and to be maintaining a steady but not extraordinary speed. Obviously the driver was taking no risks of meeting with an accident or a hold-up; it seemed too as though he had no very great fear of being followed.
The sergeant, who, when they plunged into the second-class roads, pursuing an erratic course, privately thought there was little chance of catching a car bound for an unknown destination and bearing a false nameplate, began after a little time to realise that Amberley was pushing forward to some definite point. When they stopped at Hillingdean and the sergeant conferred with a constable on point duty there, he got out a road map and studied it intently.
The warning, sent out from Upper Nettlefold, had been received by all the southern stations but bore no fruit. No car of the stated number had anywhere been seen. Amberley cursed himself for having given the fatal number and wasted no more time in inquiring for it.
There were many circuitous byways that led to the coast, so that it was hardly surprising that the sergeant should consider the chase hopeless. For miles they had no intelligence of the Vauxhall, but Amberley never slackened speed except to read a signpost here and there, and never hesitated in his choice of direction. It became increasingly apparent to the sergeant that he had a fixed goal in his mind, for it could scarcely be due to chance that they picked the trail up again twice when it had seemed completely lost.
Once Amberley bade him take the map over a difficult piece of country and guide him to some village the sergeant had never heard of. The sergeant ventured to ask where they were going. He had to raise his voice to be heard above the roar of the engine. He saw Amberley give a shrug, and managed to catch the word, "Littlehaven." It conveyed nothing to the sergeant. As the Bentley rocked over a stretch of lane pitted with holes he said: "If you're sure where he's gone, sir, why don't you take the main road?"
"Because I'm not sure, damn you!" said Mr. Amberley. "It's the best I can do."
The sergeant relapsed into silence. Except for the discomfort of travelling at a shocking pace over bad roads he was not sure that he wasn't glad they had chosen deserted lanes. At least they ran less risk of an accident. He shuddered to think what might happen on a main road. As it was he spent most of his time clutching at the door to steady himself, and although his nerves were becoming dulled, he had several bad frights. Once when a bicyclist wobbled into the middle of the road and the Bentley's wheels tore at the loose surface as it took a sudden swerve round the unwary cyclist, he was moved to shout: "People like you, Mr. Amberley, didn't ought to be allowed anything more powerful than a Ford!"
He had thought it a still night, but the wind whistled east his ears and once nearly swept his helmet off. He jammed it on more firmly and thought Mr. Amberley must be fairly scared out of his senses to treat his car in this frightful fashion.
The moon had come up and was riding serenely overhead, occasionally obscured by a drifting cloud. The country through which they were travelling was unfamiliar to the sergeant. He retained ever afterwards the memory of untarred roads with puddles gleaming in the moonlight, of hedges flashing past, of villages where warm lamps glowed behind uncurtained windows, and of signposts stretching cracked arms to point the way to unknown hamlets; of hills up which the Bentley stormed, of sudden sickening lurches as the car took a bad corner, of the electric horn insistently blaring at slower-going vehicles, forcing them to draw in to the side; and above all of Mr. Amberley's face beside him, with the eyes never wavering from the road ahead and the mouth compressed in a hard, merciless line.
