eight o'clock in the morning
Three nights of sleeplessness , anxiety and fatigue had prostrated the vital forces of the young nobleman , and so , no sooner had the train started , than he sat himself comfortably back among his cushions , and , being now in a great measure relieved from suspense , he fell into a deep and dreamless sleep . This sleep continued almost unbroken through the night , and was only slightly disturbed by the bustle of arrival when the train reached a large city on its route . He awoke when it arrived at Peterborough ; but fell asleep again , and slept through the long twilight of that first day of November . It was eight o'clock in the morning of a dark and cloudy day , when the duke was finally aroused by the noise and confusion attending the arrival of the Great Northern Express train at King 's Cross Station , London . He shook himself wide awake , adjusted his wrap , and sprang out of his coupe , while yet his servant was but just bestirring himself . The first man he met in the station was Detective Setter .
