Read it through once

As it dashed on, Oliver caught a glimpse of a man in a white nightcap, whose face seemed familiar to him, although his view was so brief that he could not identify the person. In another second or two, the nightcap was thrust out of the chaise-window, and a stentorian voice bellowed to the driver to stop: which he did, as soon as he could pull up his horses. Then, the nightcap once again appeared: and the same voice called Oliver by his name.
