‘Yes, I say it, and I mean it. I visited your observatory last night.’

‘You did, my lord.’

‘In inspecting it I noticed something which I may truly describe as extraordinary. I have had young men present themselves to me who turned out to be notoriously unfit, either from giddiness, from being profane or intemperate, or from some bad quality or other. But I never remember a case which equalled the cool culpability of this. While infringing the first principles of social decorum you might at least have respected the ordinance sufficiently to have stayed away from it altogether. Now I have sent for you here to see if a last entreaty and a direct appeal to your sense of manly uprightness will have any effect in inducing you to change your course of life.’

The voice of Swithin in his next remark showed how tremendously this attack of the Bishop had told upon his feelings. Louis, of course, did not know the reason why the words should have affected him precisely as they did; to any one in the secret the double embarrassment arising from misapprehended ethics and inability to set matters right, because his word of secrecy to another was inviolable, would have accounted for the young man’s emotion sufficiently well.

‘I am very sorry your lordship should have seen anything objectionable,’ said Swithin. ‘May I ask what it was?’

‘You know what it was. Something in your chamber, which forced me to the above conclusions. I disguised my feelings of sorrow at the time for obvious reasons, but I never in my whole life was so shocked!’

‘At what, my lord?’

‘At what I saw.’

‘Pardon me, Bishop Helmsdale, but you said just now that we are strangers; so what you saw in my cabin concerns me only.’

‘There I contradict you. Twenty-four hours ago that remark would have been plausible enough; but by presenting yourself for confirmation at my hands you have invited my investigation into your principles.’
