[Advancing to PROFESSOR RUBEK's table and politely taking off his hat.] I have the honour to wish you good morning, Mrs. Rubek.—Good morning, Professor Rubek.

Good morning, good morning Inspector.

[Addressing himself to MRS. RUBEK.] May I venture to ask if you have slept well?

Yes, thank you; excellently—for my part. I always sleep like a stone.

I am delighted to hear it. The first night in a strange place is often rather trying.—And the Professor—?

Oh, my night's rest is never much to boast of—especially of late.

[With a show of sympathy.] Oh—that is a pity. But after a few weeks' stay at the Baths—you will quite get over that.

[Looking up at him.] Tell me, Inspector—are any of your patients in the habit of taking baths during the night?

[Astonished.] During the night? No, I have never heard of such a thing.

Have you not?
