In the doctor's mind so many broken sentences began with that will-o'-the-wisp among words, that others really spoken fell upon stony ears, and he knew as little what he said in reply. In a dream he saw a small hand wave as the taxicab vanished round the corner to the right; in a dream he sprang up-stairs, hiding under his coat the weapon with which that little hand had dealt out death; and awoke in his wintriest clothes, his greatest coat, to find himself called upon to top the lot with another of unkempt fur sent with the car. That aluminum clipper--a fifteen-horse-power Invincible Talboys--was indeed at the door in incredibly quick time. Twin headlights lit long wedges of London mud; two pairs of goblin goggles mounted up behind them--one sent with the coat and a message that was more than law. The dapper chauffeur huddled down behind the wheel; the passenger sat bolt upright at his side; the Barton family, his faithful creatures, carried out an impromptu tableau in the background. Mother and son--those unpresentable features of a former occasion--now appeared as immaculate cook and page at the top of the area steps and on the lighted threshold respectively. Barton himself leaned out of an upper window, still in his white suit--it was the typically muggy Christmas of a degenerate young century--but with all the black cares of the strange establishment quite apparent on his snowy shoulders. The dapper driver gave his horn a spiteful pinch. And then they were off, only to be held up in Oxford Street by the Christmas traffic, but doing better in the Edgware Road, and soon on the way to Edgware itself, and Elstree and St. Albans, and all the lighted towns and pitch-dark roads that lie by night between the capital of England and her smallest county. "Least trem-lines this wye," said the dapper one, a mile or two out; and said no more for another fifty. But he drove like a little genius, and the car responded to his cunning hands as a horse that knows its master. She proved to be a sound roadster whose only drawback was a lack of racing speed; the lad had her in prime condition, and the good road ran from under her like silk from a silent loom. Dollar sat beside him, in the shelter of a wind-screen that glazed and framed a continuous study in nocturnal values. Now the fine shades would be broken by a cluster of lights, soon to scatter and go out like sparks from a pipe; now only by the acetylene lamps that kept the foreground in a blaze between villages. Often a ghostly portent appeared hovering over the road ahead; but this was only the doctor's own anxious face, seen dimly in the screen.
