It was nearly seven o'clock when he reached Euston Square; and he only got to the Paddington station in time to hear that the last train for Marlingford had just started. There was no possibility of his reaching the little Berkshire village that night. No mail-train stopped within a reasonable distance of the obscure station. There was no help for it, therefore, Captain Arundel had nothing to do but to wait for the next morning.

He walked slowly away from the station, very much disheartened by this discovery.

"I'd better sleep at some hotel up this way," he thought, as he strolled listlessly in the direction of Oxford Street, "so as to be on the spot to catch the first train to-morrow morning. What am I to do with myself all this night, racked with uncertainty about Mary?"

He remembered that one of his brother officers was staying at the hotel in Covent Garden where Edward himself stopped, when business detained him in London for a day or two.

"Shall I go and see Lucas?" Captain Arundel thought. "He's a good fellow, and won't bore me with a lot of questions, if he sees I've something on my mind. There may be some letters for me at E——'s. Poor little Polly!"

He could never think of her without something of that pitiful tenderness which he might have felt for a young and helpless child, whom it was his duty and privilege to protect and succour. It may be that there was little of the lover's fiery enthusiasm mingled with the purer and more tender feelings with which Edward Arundel regarded his dead friend's orphan daughter; but in place of this there was a chivalrous devotion, such as woman rarely wins in these degenerate modern days.

The young soldier walked through the lamp-lit western streets thinking of the missing girl; now assuring himself that his instinct had not deceived him, and that Mary must have gone straight to the Berkshire farmer's house, and in the next moment seized with a sudden terror that it might be otherwise: the helpless girl might have gone out into a world of which she was as ignorant as a child, determined to hide herself from all who had ever known her. If it should be thus: if, on going down to Marlingford, he obtained no tidings of his friend's daughter, what was he to do? Where was he to look for her next?

He would put advertisements in the papers, calling upon his betrothed to trust him and return to him. Perhaps Mary Marchmont was, of all people in this world, the least likely to look into a newspaper; but at least it would be doing something to do this, and Edward Arundel determined upon going straight off to Printing-House Square, to draw up an appeal to the missing girl.

It was past ten o'clock when Captain Arundel came to this determination, and he had reached the neighbourhood of Covent Garden and of the theatres. The staring play-bills adorned almost every threshold, and fluttered against every door-post; and the young soldier, going into a tobacconist's to fill his cigar-case, stared abstractedly at a gaudy blue-and-red announcement of the last dramatic attraction to be seen at Drury Lane. It was scarcely strange that the Captain's thoughts wandered back to his boyhood, that shadowy time, far away behind his later days of Indian warfare and glory, and that he remembered the December night upon which he had sat with his cousin in a box at the great patent theatre, watching the consumptive supernumerary struggling under the weight of his banner. From the box at Drury Lane to the next morning's breakfast in Oakley Street, was but a natural transition of thought; but with that recollection of the humble Lambeth lodging, with the picture of a little girl in a pinafore sitting demurely at her father's table, and meekly waiting on his guest, an idea flashed across Edward Arundel's mind, and brought the hot blood into his face.

What if Mary had gone to Oakley Street? Was not this even more likely than that she should seek refuge with her kinsfolk in Berkshire? She had lived in the Lambeth lodging for years, and had only left that plebeian shelter for the grandeur of Marchmont Towers. What more natural than that she should go back to the familiar habitation, dear to her by reason of a thousand associations with her dead father? What more likely than that she should turn instinctively, in the hour of her desolation, to the humble friends whom she had known in her childhood?
