'Never you fear, sir,' said the guard, 'we won't go without them, but I'll call 'em; they'll mind me more than they will you, beggin' your pardon, sir, and you'd better run on, as time's short, and keep places for 'em. You leave it all to me; I'll take care on 'em.'

Mark heard faint barks across the hedge in the direction Mabel had taken. The child was evidently found. The best thing, he thought, to do now was to secure an empty compartment, and with that idea, and perhaps a little from that instinctive obedience to anything in a uniform which is a characteristic of the average respectable Englishman, he let himself be persuaded by the guard, and went back to the train.

To his great joy he found that the compartment Mabel had occupied had no one in it; he stood waiting by the door for Mabel and her sister to come up, with eager anticipations of a delightful conclusion to his journey. 'Perhaps she will tell me who she is,' he thought; 'at all events she will ask me who I am. How little I hoped for this yesterday!'

He was interrupted by a guard—another guard, a sour-looking man with a grizzled beard, who was in charge of the front van. 'Get in, sir, if you mean to travel by this 'ere train,' he said.

'I'm waiting for a young lady,' said Mark, rather ingenuously, but it slipped out almost without his knowledge. 'The other guard promised me——'

'I don't know nothing about no young ladies,' said the guard obdurately; 'but if you mean my mate, he's just give me the signal from his end, and if you don't want to be left be'ind you'd better take your seat while you can, sir, and pretty sharp, too.'

There was nothing else to do; he could not search for Mabel along the train; he must wait till they got to King's Cross; but he took his seat reluctantly and with a heavy disappointment, thinking what a fool he had been to let himself be persuaded by the burly guard. 'But for that, she might have been sitting opposite to me now!' he thought bitterly. 'What a fool I was to leave her. How pretty she looked when she wanted me to see a doctor; how charming she is altogether! Am I in love with her already? Of course I am; who wouldn't be? I shall see her again. She will speak to me once more, and, after all, things might be worse. I couldn't have counted on that when we started.'

And he tried to console himself with this, feeling an impatient anger at the slow pace of the train as it crept cautiously on towards the goal of his hopes. But the breakdown had not happened very far from town, and, tedious as the time seemed to Mark, it was not actually long before the colour of the atmosphere (there was no other indication) proved that they were nearing the terminus.

It changed by slow gradations from its original yellow-whiteness to mustard colour, from that to a smoky lurid red, and from red to stinging, choking iron-grey, and the iron-grey pall was in full possession of King's Cross, where the sickly moonlight of the electric lamps could only clear small halos immediately around their globes.

Mark sprang out before the train had stopped; he strained his eyes in watching for the form he hoped to see there, but in vain; there were no signs in all that bustle of Mabel or Dolly, or the little dog to whom he owed so much.
