‘Hide behind the screen again!’ whispered Mercia, ‘no one knows thou art here; it is easy enough to do; and thou canst report upon the manner in which I am treated, if need be—dost understand?’

‘Perfectly, I will do it, and come out if I see necessary,’ agreed the old man with a roguish beam in his eyes, while he slipped behind in a twinkle. He had no sooner disappeared than the constables entered the apartment, which they did in a somewhat hesitating manner. Evidently, they did not at all relish their work, for the inmates of the Observatory, as well as the place itself inspired them with respect.

‘Why this intrusion on a lady in her private apartment?’ demanded Geometrus haughtily; for he considered they ought to have remained in the entrance hall, until their errand was explained.

‘What is your wish?’ inquired Mercia in quiet tones.

‘Mistress, I have brought with me a document, an ugly document, truly, to show a lady, and to such a one as thou it is indeed vexatious to have the handling of it. Nevertheless, it has been entrusted to me, and obedience is the first great principle of all order. Therefore, very unwillingly, I confess, I call upon thee in the Emperor’s name to surrender thyself—here is my authority,’ and he held out the warrant for her perusal, still keeping his hold of it. When she had finished, she stood for a moment thinking, whereupon he stepped forward to lead her away, when Mercia falling back a little, drew herself up haughtily, and exclaimed—‘Touch me not, fellow, I will leave this house of mine own accord when I am fully prepared for my journey, for I must attire myself suitably before going into the night air, also my carriage must be made ready for me.’

‘We have brought the ordinary police-van by special order of the Emperor, we dare not let any other be used,’ interpolated another officer, for there were three of them.

‘The police-van for me!’ repeated Mercia indignantly, ‘and by the Emperor’s orders too! What has the Emperor to do with the administration of the law? I refuse to obey such an order.’

‘And rightly so,’ interjected Geometrus hotly, then turning with furious face upon the constables, he added—‘This lady goes with you in her own carriage, or not at all.’

‘What is that to thee?’ returned the sergeant of police sharply, ‘a pretty person to lay down conditions to us, and dictate how we are to perform our duty, seeing thou art in the same boat thyself. Here is the warrant for thy apprehension; and get thee ready quickly.’

‘If you touch her, any of you, against her will, I will strike him dead with my electric dagger!’ shouted Geometrus, who was beside himself with anger.
