It was now pitch dark, and a driving, biting storm of snow and hail was blowing across their path from the east. When the constable-_chauffeur_ had learned sufficient of the car to give him confidence, the storm had swept down, and their progress had been scarcely any faster. There had been delays, too. By Ripley a heavy farm waggon had broken down almost before their eyes, and it had been ten minutes before a spare chain horse could be obtained to drag it to the roadside. Further on some men felling a tree in a coppice had clumsily allowed it to fall across the road, and another ten minutes elapsed before it was cut in two and rolled aside. Fortunately they were not pressed for time. Fortunately, also, the driver knew the way, for few people were afoot to face that dreadful stream of snow and ice with the lashing wind and the numbing cold. Two, two or three, or perhaps four men had chanced to be at hand when the car stopped, making their way towards the bridge, but the wreathing snow soon cut them off. Occasionally, when the wind and drift hung for a moment, a figure or two showed dimly and gigantic in the murk of the tunnel. Nothing of the fire could be seen, but the smoke continued to pour out, and the mingled odour of burned and unburned oil filled the car. In a few minutes the driver returned. When he had left his seat Moeletter had leaned forward, and with a gruff word of half apology had laid a hand upon the rug across Salt's knees, so that he held, or at least controlled, the connecting links of the handcuffs, while at the same time his other hand had dropped quietly down to his hip-pocket. He now lowered the window on the further side, still keeping his left hand on the rug. "Oil cart ablaze, sir," gasped the driver, between paroxysms of coughing. "Road simply running fire, and the fumes awful." His face was almost completely protected beneath cap, goggles, and a storm shade that fell from the cap over the shoulders and buttoned across the mouth, but no covering had seemed effectual against the suffocating reek of the burning oil. The fire had melted the snow off his clothes, and he stood by the door with a bar of darkness just falling across his face, and the electric light through the lowered window blazing upon his gleaming leathers, his gauntlets and puttee leggings, and the cumbrous numbered badge that the regulations then imposed. "It will be some time before the road is passable?" asked Moeletter with a frown. "Oh, hours perhaps," was the sputtering reply. "Would suggest going by Molesey Bridge, sir. Best way now." "Is it much out?" "The turning is half a mile back. From there it is no further than this way." "And you know the way perfectly?" The driver nodded. "Perfectly, sir." "Very well; go on. We have plenty of time yet, but you might get a few more miles out of her, if you think you can."
