'Without a doubt,' replied the latter, stepping back, 'Monsieur le Marchand de dentelles.'

It was Kelly's turn to be startled, and that he was effectually; he was shocked into a complete recovery of his senses and an accurate estimation of his folly. He walked to the entrance and stood upon the steps. The executioner knew him, knew something of his trade. Who, then, was M. de Strasbourg? Kelly recalled the tones of his voice, conned them over in his mind, and was not a penny the wiser. He glanced backwards furtively across his shoulder and looked the man over from head to foot.

At that moment a carriage drove up to the entrance. Mr. Kelly was standing on the top of the steps and the face of the coachman on the box was just on a level with his own. He stared, in a word, right at it, and so took unconsciously an impression of it upon his mind, while pondering how he should act with regard to M. de Strasbourg. Consequently he did not notice that a woman stepped out of the carriage and, without looking to the right or left, quickly mounted the steps. His eyes, in fact, were still fixed upon the coachman's face; and it needed the brushing of her cloak against his legs to rouse him from his reflections.

He turned about just as she disappeared at the far end of the lobby. He caught a glimpse of a white velvet cloak and an inch of blue satin petticoat under a muffling domino. He also saw that M. de Strasbourg was drawn close behind a pillar, as though he wished to avoid the lady. As soon, however, as she had vanished he came boldly out of his concealment and followed her into the theatre. Mr. Kelly began instantly to wonder whether a closer view of the domino would help him discover who M. de Strasbourg really was, and entering the theatre he went up into the boxes.

At first his eyes were bedazzled by the glitter of lights and jewels and the motley throng which paraded the floor. There was the usual medley of Chinese, Turks, and friars; here was a gentleman above six feet high dressed like a child in a white frock and leading strings and attended by another of very low stature, who fed him from time to time with a papspoon; there was a soldier prancing a minuet upon a hobby horse to the infinite discomfort of his neighbours; and as for the women--it seemed to Mr. Kelly that all the goddesses of the heathen mythology had come down from Olympia in their customary négligé.

Among them moved M. de Strasbourg like a black shadow, very distinguishable. Kelly kept his eyes in the man's neighbourhood, and in a little perceived a masked lady with her hair dressed in the Greek fashion. What character she was intended to represent he could not for the life of him determine. He learnt subsequently that she went as Iphigeneia--Iphigeneia, if you please, in a blue satin petticoat. To be sure her bosom was bared for the sacrifice, but then all the ladies in that assembly were in the like case. She had joined a party of friends, of whom M. de Strasbourg was not one. For though he kept her ever within his sight, following her hither and thither, it was always at a distance; and, so far as Kelly could see, and he did not take his eyes from the pair, he never spoke to her so much as a single word. On the contrary he seemed rather to lurk behind and avoid her notice. Kelly's curiosity was the more provoked by this stealthy pursuit. He lost his sense of uneasiness in a wonder what the man designed against the woman. He determined to wait the upshot of the affair.

The night wore away, the masqueraders thinned. The inch of blue satin petticoat took her departure from the parterre. M. de Strasbourg followed her; Mr. Kelly followed M. de Strasbourg.

The lobby was crowded. Kelly threaded his way through the crowd and came out upon the steps. He saw the lady, close wrapped again in her velvet cloak, descend to her carriage. The coachman gathered up his reins and took his whip from its rest. The movement chanced to attract Kelly's eyes. He looked at the coachman, at the first glance indifferently, at the second with all his attention. For this was not the same man who had driven the carriage to the masquerade. And then the coachman turned his full face towards Kelly and nodded. He nodded straight towards him. But was the nod meant for him? No! Well, then, for someone just behind his shoulder.

Kelly did not turn, but stepped quietly aside and saw M. de Strasbourg slip past him down the steps. So the nod was meant for him. M. de Strasbourg was still masked, but he had thrown a cloak about his shoulders which in some measure disguised his dress. The mystery seemed clear to Kelly; the lady was to be forcibly abducted unless someone, say Mr. James Johnson, had a word to say upon the matter. The carriage turned and drove slowly through the press of chairs and shouting link-boys; M. de Strasbourg on the side-walk kept pace with the carriage. Kelly immediately crossed the road, and, concealed by the carriage, kept pace with M. de Strasbourg. Thus they went as far as the corner of the Haymarket, and then turned into Pall Mall.

At this point Kelly, to be the more ready should the lady need his assistance, stepped off the pavement and walked in the mud hard by the hind wheels of the carriage. It was now close upon four of the morning, but, fortunately, very dark, and only a sullen sort of twilight about the south-eastern fringes of the sky.
