II.THE MAIL
I t was the Dover road that lay，on a Friday night late in November，before the first of the persons with whom this history has business. The Dover road lay，as to him，beyond the Dover mail，as it lumbered up Shooter's Hill.He walked uphill in the mire by the side of the mail，as the rest of the passengers did；not because they had the least relish for walking exercise，under the circumstances，but because the hill，and the harness，and the mud，and the mail，were all so heavy，that the horses had three times already come to a stop，besides once drawing the coach across the road，with the mutinous intent of taking it back to Blackheath.Reins and whip and coachman and guard，however，in combination，had read that article of war which forbade a purpose otherwise strongly in favour of the argument，that some brute animals are endued with Reason；and the team had capitulated and returned to their duty.
With drooping heads and tremulous tails，they mashed their way through the thick mud，floundering and stumbling between whiles，as if they were falling to pieces at the larger joints. As often as the driver rested them and brought them to a stand，with a wary'Wo-ho！so-ho then！'the near leader violently shook his head and everything upon it—like an unusually emphatic horse，denying that the coach could be got up the hill.Whenever the leader made this rattle，the passenger started，as a nervous passenger might，and was disturbed in mind.
There was a steaming mist in all the hollows，and it had roamed in its forlornness up the hill，like an evil spirit，seeking rest and finding none. A clammy and intensely cold mist，it made its slow way through the air in ripples that visibly followed and overspread one another，as the waves of an unwholesome sea might do.It was dense enough to shut out everything from the light of the coach-lamps but these its own workings and a few yards of road；and the reek of the labouring horses steamed into it，as if they had made it all.
Two other passengers，besides the one，were plodding up the hill by the side of the mail. All three were wrapped to the cheek-bones and over the ears，and wore jack-boots.Not one of the three could have said，from anything he saw，what either of the other two was like；and each was hidden under almost as many wrappers from the eyes of the mind，as from the eyes of the body，of his two companions.In those days，travellers were very shy of being confidential on a short notice，for anybody on the road might be a robber or in league with robbers.As to the latter，when every posting-house and ale-house could produce somebody in'the Captain's'pay，ranging from the landlord to the lowest stable nonde，it was the likeliest thing upon the cards.So the guard of the Dover mail thought to himself，that Friday night in November，one thousand seven hundred and seventy-five，lumbering up Shooter's Hill，as he stood on his own particular perch behind the mail，beating his feet，and keeping an eye and a hand on the arm-chest before him，where a loaded blunderbuss lay at the top of six or eight loaded horse-pistols，deposited on a substratum of cutlass.
The Dover mail was in its usual genial position that the guardsuspected the passengers，the passengers suspected one another and the guard，they all suspected everybody else，and the coachman was sure of nothing but the horses；as to which cattle he could with a clear conscience have taken his oath on the two Testaments that they were not fit for the journey.
'Wo-ho！'said the coachman.'So，then！One more pull and you're at the top and be damned to you，for I have had trouble enough to get you to it！—Joe！'
'Halloa！'the guard replied.
'What o'clock do you make it，Joe？'
'Ten minutes，good，past eleven.'
'My blood！'ejaculated the vexed coachman，'and not atop of Shooter's yet！Tst！Yah！Get on with you！'
The emphatic horse，cut short by the whip in a most decided negative，made a decided scramble for it，and the three other horses followed suit. Once more，the Dover mail struggled on，with the jack-boots of its passengers squashing along by its side.They had stopped when the coach stopped，and they kept close company with it.If any one of the three had had the hardihood to propose to another to walk on a little ahead into the mist and darkness，he would have put himself in a fair way of getting shot instantly as a highwayman.
The last burst carried the mail to the summit of the hill. The horses stopped to breathe again，and the guard got down to skid the wheel for the descent，and open the coach-door to let the passengers in.
'Tst！Joe！'cried the coachman in a warning voice，looking down from his box.
'What do you say，Tom？'
They both listened.
'I say a horse at a canter coming up，Joe.'
'I say a horse at a gallop，Tom，'returned the guard，leaving his hold of the door，and mounting nimbly to his place.'Gentlemen！In the King's name，all of you！'
With this hurried adjuration，he cocked his blunderbuss，and stood on the offensive.
The passenger booked by this history，was on the coachstep，getting in；the other two passengers were close behind him，and about to follow. He remained on the step，half in the coach and half out of it；they remained in the road below him.They all looked from the coachman to the guard，and from the guard to the coachman，and listened.The coachman looked back and the guard looked back，and even the emphatic leader pricked up his ears and looked back，without contradicting.
The stillness consequent on the cessation of the rumbling and labouring of the coach，added to the stillness of the night，made it very quiet indeed. The panting of the horses communicated a tremulous motion to the coach，as if it were in a state of agitation.The hearts of the passengers beat loud enough perhaps to be heard；but at any rate，the quiet pause was audibly expressive of people out of breath，and holding the breath，and having the pulses quickened by expectation.
The sound of a horse at a gallop came fast and furiously up the hill.
