DOCTOR. Take this conjuring, for instance. You know the Duke has two wards who are to live with him now? SMITH. Yes. I heard something about a nephew and niece from Ireland. DOCTOR. The niece came from Ireland some months ago, but the nephew comes back from America to-night. [_He gets up abruptly and walks about the room._] I think I will tell you all about it. In spite of your precious public-house you seem to me to be a sane man. And I fancy I shall want all the sane men I can get to-night. SMITH. [_Rising also._] I am at your service. Do you know, I rather guessed you did not come here only to protest against my precious public-house. DOCTOR. [_Striding about in subdued excitement._] Well, you guessed right. I was family physician to the Duke's brother in Ireland. I knew the family pretty well. SMITH. [_Quietly._] I suppose you mean you knew something odd about the family? DOCTOR. Well, they saw fairies and things of that sort. SMITH. And I suppose, to the medical mind, seeing fairies means much the same as seeing snakes? DOCTOR. [_With a sour smile._] Well, they saw them in Ireland. I suppose it's quite correct to see fairies in Ireland. It's like gambling at Monte Carlo. It's quite respectable. But I do draw the line at their seeing fairies in England. I do object to their bringing their ghosts and goblins and witches into the poor Duke's own back garden and within a yard of my own red lamp. It shows a lack of tact. SMITH. But I do understand that the Duke's nephew and niece see witches and fairies between here and your lamp. [_He walks to the garden window and looks out._ DOCTOR. Well, the nephew has been in America. It stands to reason you can't see fairies in America. But there is this sort of superstition in the family, and I am not easy in my mind about the girl. SMITH. Why, what does she do? DOCTOR. Oh, she wanders about the park and the woods in the evenings. Damp evenings for choice. She calls it the Celtic twilight. I've no use for the Celtic twilight myself. It has a tendency to get on the chest. But what is worse, she is always talking about meeting somebody, some elf or wizard or something. I don't like it at all. SMITH. Have you told the Duke? DOCTOR. [_With a grim smile._] Oh, yes, I told the Duke. The result was the conjurer. SMITH. [_With amazement._] The _conjurer_?
