RIDGEON. Send a drop of the patient's blood to the laboratory at
St. Anne's; and in fifteen minutes I'll give you his opsonin
index in figures. If the figure is one, inoculate and cure: if
it's under point eight, inoculate and kill. Thats my discovery:
the most important that has been made since Harvey discovered the
circulation of the blood. My tuberculosis patients dont die now.

SIR PATRICK. And mine do when my inoculation catches them in the
negative phase, as you call it. Eh?

RIDGEON. Precisely. To inject a vaccine into a patient without
first testing his opsonin is as near murder as a respectable
practitioner can get. If I wanted to kill s man I should kill him
that way.

EMMY [looking in] Will you see a lady that wants her husband's
lungs cured?

RIDGEON [impatiently] No. Havnt I told you I will see nobody?[To
Sir Patrick] I live in a state of siege ever since it got about
that I'm a magician who can cure consumption with a drop of
serum. [To Emmy] Dont come to me again about people who have no
appointments. I tell you I can see nobody.

EMMY. Well, I'll tell her to wait a bit.

RIDGEON [furious] Youll tell her I cant see her, and send her
away: do you hear?
