There was no question of an accidental likeness; it was the girl herself, and he recognised the dress as one he had seen her wear. Turning sharply on his heel he turned down a bye street, and came out into Upper Street. There were too many people here for him to think; he passed on, walking in the road at the edge of the pavement, to the Angel, and then turned down the comparatively quiet pavement of Pentonville Hill.

What could it mean? He could see but one solution, and yet he refused to accept it. To believe it was to believe Dorothy Hawtrey to be guilty of deception and lying. Was it possible that, after all, this man could have possessed letters of hers, and that she had been driven at last to meet him and redeem them? He remembered her pallor when she had heard that morning that this fellow's whereabouts had been discovered, and how she had urged that no steps should be taken against him. It had all seemed natural then; it seemed equally natural now under this new light—and yet he refused to believe it. So he told himself over and over again. That he had seen her in conversation with Truscott was undeniable; of that, at least, he was certain, but equally certain was it to him that there must be some other explanation of the meeting than that which had at first struck him. What could that explanation be? No answer occurred to him; he could hit upon no hypothesis consistent with her denial of any knowledge whatever of the writer of these letters.

He was at the bottom of the hill now; disregarding the hails of various cabmen, he crossed the road and made his way down through the squares. It was better to be walking than sitting still. He scarcely noticed where he was going, and was almost surprised when he found himself in Jermyn Street. He went upstairs, lighted a cigar, and sat down.

'What is coming to me?' he said to himself. 'I am generally pretty good at guessing riddles, and there must be some explanation of this mystery, if I can but hit upon it.'

But after thinking for another hour, the only alternative to the first idea that had occurred to him was that Dorothy, in her horror of the idea of a public trial and of being forced to appear in the witness box, had taken the desperate resolution to find this man herself, at the address he had mentioned to her and her father, to bribe him to desist from his persecution of her, and to warn him that unless he moved away at once the police would be on his track.

It was all so unlike the high-spirited child he had known, and the girl as he had believed her still to be, that it was difficult to credit that she would allow herself to be driven to take such a step as this, in order to escape what seemed to him a minor unpleasantness.

Still, as he told himself, there were men of tried bravery in many respects who were moral cowards, and it might well be that, though generally fearless, Dorothy might have a nervous shrinking from the thought of standing up in a crowded court, exposed to an inquisition that in many cases was almost a martyrdom. It was an awful mistake to have made. If the scoundrel had been bribed into silence now, he would be all the more certain to recommence his persecution later on, and after having once met with and paid him for his silence how could she refuse to do so when another demand was made?

One thing seemed to Ned Hampton unquestionable. He must maintain an absolute silence as to what he had seen—the harm was done now and could not be undone. He was certain that she had not noticed him, and could never suspect that he had her secret. As for himself there was nothing for him now but to stand aside altogether. Filled as he was with the deepest pity for Dorothy, he was powerless to help her. When the next trouble came it was her husband who would have to stand beside her, and to whom, sooner or later, she would have to own the false step she had taken.

He felt that at any rate it was out of the question that he should see her again at present. It was fortunate that he had retired from the investigation in favour of Mr. Slippen, and could therefore run away for a bit without seeming to have deserted Mr. Hawtrey. He had thought about hiring a yacht, and this would serve as a pretext for him to run down to Ryde. He could easily put away a fortnight between that town, Cowes, Southampton, and Portsmouth. As to the yacht he had no real intention now of looking for one. He must wait for a while and see what happened next. He was sure to meet men he knew at Southsea, and anything was better than staying in London.

He accordingly at once wrote a note to Mr. Hawtrey, saying that it would be some time before Slippen obtained such evidence against Truscott as would put them in a position to bring it home to him, and that as he could not be of any use for a time he had resolved to run down for a week to Southsea, and look round the various yards in search of a yacht of about the size he wanted, for a cruise of six weeks or two months, with the option of taking her up the Mediterranean through the winter. Then he wrote several letters of excuse to houses where he had engagements, and started the next morning by the first train for Portsmouth. He was a fortnight absent, and on his return called on Mr. Hawtrey at an hour when he knew that he was not likely to meet Dorothy.
