CONJURER. Oh, of course. People in delirium always keep secrets
strictly.

DOCTOR. No one sees the patient but his sister and myself.

CONJURER. [_Starts slightly._] Yes, his sister. Is she very anxious?

DOCTOR. [_In a lower voice._] What would you suppose?

[CONJURER _throws himself into the chair, his cloak slipping back
from his evening dress. He ruminates for a short space and then
speaks._

CONJURER. Doctor, there are about a thousand reasons why I should not
tell you how I really did that trick. But one will suffice, because it
is the most practical of all.

DOCTOR. Well? And why shouldn't you tell me?

CONJURER. Because you wouldn't believe me if I did.

[_A silence, the_ DOCTOR _looking at him curiously._

[_Enter the_ DUKE _with papers in his hand. His usual gaiety of

CONJURER.] Now, my dear sir, I hope you will not be offended if I say
that this ought to be a business matter. We are asking you for a piece
of your professional work and knowledge, and if I may have the pleasure

CONJURER. I thank your Grace, I have already received my cheque from
your secretary. You will find it on the counterfoil just after the
cheque you so kindly gave to the Society for the Suppression of
Conjuring.

DUKE. Now I don't want you to take it in that way. I want you to take
