o come and look at him, Professor CALWAY.
He's in there.

[She points towards the model's room. CALWAY smiles
deprecatingly.]

ANN. No, really; we needn't open the door. You can see him through
the glass. He's more than half----

CALWAY. Well, I hardly----

ANN. Oh! Do! Come on, Professor CALWAY! We must know what to do
with him. [CALWAY rises.] You can stand on a chair. It's all
science.

[She draws CALWAY to the model's room, which is lighted by a
glass panel in the top of the high door. CANON BERTLEY also
rises and stands watching. WELLWYN hovers, torn between
respect for science and dislike of espionage.]

ANN. [Drawing up a chair.] Come on!

CALWAY. Do you seriously wish me to?

ANN. Rather! It's quite safe; he can't see you.

CALWAY. But he might come out.

[ANN puts her back against the door. CALWAY mounts the chair
dubiously, and raises his head cautiously, bending it more and
more downwards.]

ANN. Well?

CALWAY. He appears to be---sitting on the floor.

WELLWYN. Yes, that's all right!

[BERTLEY covers his lips.]

CALWAY. [To ANN--descending.] By the look of his face, as far as
one can see it, I should say there was a leaning towards mania. I
know the treatment.

[There come three loud knocks on the door. WELLWYN and ANN
exchange a glance of consternation.]

ANN. Who's that?

WELLWYN. It sounds like Sir Thomas.

CALWAY. Sir Thomas Hoxton?

WELLWYN. [Nodding.] Awfully sorry, Professor. You see, we----

CALWAY. Not at all. Only, I must decline to be involved in
argument with him, please.

BERTLEY. He has experience. We might get his opinion, don't you
think?

CALWAY. On a point of reform? A J.P.!

BERTLEY. [Deprecating.] My dear Sir--we needn't take it.

[The three knocks resound with extraordinary fury.]

ANN. You'd better open the door, Daddy.

[WELLWYN opens the door. SIR, THOMAS HOXTON is disclosed in a
fur overcoat and top hat. His square, well-coloured face is
remarkable for a massive jaw, dominating all that comes above
it. His Voice is resolute.]

HOXTON. Afraid I didn't make myself heard.

WELLWYN. So good of you to come, Sir Thomas. Canon Bertley! [They
greet.] Professor CALWAY you know, I think.

HOXTON. [Ominously.] I do.

[They almost greet. An awkward pause.]

ANN. [Blurting it out.] That old cabman I told you
