Robina averted her head, for there was a general halt and a silence, and a voice made itself heard, explaining that here was the Roman masonry.

The Castle was a large place, containing the county hall, and having likewise a small garrison of artillery to take care of the sea defences, on which modern science had of late been busy. The lecturer led his flock literally from pillar to post, stopping to expound all points of interest, and handing round drawings and photographs. There was nothing to do but to follow, and hope to fall in with some of the others. Of Geraldine there was no hope; old Sir Vesey had tucked her under his vigorous arm as soon as she stepped out of the carriage; Lord de Vigny had claimed her as an acquaintance, and her lameness gave her brevet rank for the nonce, for she was thrust into the forefront among the dames of high estate, and had a near view of everything. Felix had vanished; and Will, whose arm would have been very convenient to Robina in the throng, hung a little aloof, wearing an almost quaintly desperate air of surliness, while Lord Ernest hovered close, speaking to her at every pause in the lecture.

This uncomfortable trio were far in the rear, and a good deal jostled about, without very clear ideas where they were going or what they were seeing. Now it was along a moat; now out on a rampart with a green slope open to the sea, a very living looking cannon in the embrasures; now gazing up to a machicolated turret, then dragged up its spiral stair to be handed out on a leaden roof, and get a grand view, and a general impression that one of the King Henrys had done something there; then diving down to a doleful dungeon, where somebody had been starved to death, but as it was not true, it did not signify who it was. Such were all the ideas that Robina or either of her cavaliers could have given of their perambulation of Ewmouth Castle. It was lucky for the Pursuivant that they were not its caterers.

By the time she had ascended a dusky stair into the great hall of columns, which had never been a chapel, Robina found that the tour was ended, and moreover that Will—as well as all the rest—had been lost in the throng, and that no one was near whom she knew but Ernest de la Poer.

'I wonder where they all are!'

'We had better stand near the door,' he answered; 'they must pass this way.'

They waited while the stream of people flowed past; and when an acquaintance came, who was going to shake hands with Robina's companion as one of the many brothers, she piteously asked for tidings of her party.

'I saw Miss Underwood in Lady Hammond's carriage at the other door.'

'That accounts for it,' said Lord Ernest; 'I saw there was an eddy in the flood. Shall we go across?'

The move was a relief, and Robina hoped to find Felix waiting for her at the other door, for the hall was emptying fast, and they were the last to make their exit by the opposite porch. Not only were the carriages gone, but the foot-passengers; and the policemen were shutting the doors behind them, so that there was no returning across the hall.
