They come into the middle of the room together, taking off their gloves. RIDGEON. Whats the matter! Have you been sent for, too? WALPOLE. Weve all been sent for. Ive only just come: I havnt seen him yet. The charwoman says that old Paddy Cullen has been here with B. B. for the last half-hour. [Sir Patrick, with bad news in his face, enters from the inner room]. Well: whats up? SIR PATRICK. Go in and see. B. B. is in there with him. Walpole goes. Ridgeon is about to follow him; but Sir Patrick stops him with a look. RIDGEON. What has happened? SIR PATRICK. Do you remember Jane Marsh's arm? RIDGEON. Is that whats happened? SIR PATRICK. Thats whats happened. His lung has gone like Jane's arm. I never saw such a case. He has got through three months galloping consumption in three days. RIDGEON. B. B. got in on the negative phase. SIR PATRICK. Negative or positive, the lad's done for. He wont last out the afternoon. He'll go suddenly: Ive often seen it. RIDGEON. So long as he goes before his wife finds him out, I dont care. I fully expected this. SIR PATRICK [drily] It's a little hard on a lad to be killed because his wife has too high an opinion of him. Fortunately few of us are in any danger of that. Sir Ralph comes from the inner room and hastens between them, humanely concerned, but professionally elate and communicative. B. B. Ah, here you are, Ridgeon. Paddy's told you, of course. RIDGEON. Yes. B. B. It's an enormously interesting case. You know, Colly, by Jupiter, if I didnt know as a matter of scientific fact that I'd been stimulating the phagocytes, I should say I'd been stimulating the other things. What is the explanation of it, Sir Patrick? How do you account for it, Ridgeon? Have we over-stimulated the phagocytes? Have they not only eaten up the bacilli, but attacked and destroyed the red corpuscles as well? a possibility suggested by the patient's pallor. Nay, have they finally begun to prey on the lungs themselves? Or on one another? I shall write a paper about this case. Walpole comes back, very serious, even shocked. He comes between B. B. and Ridgeon. WALPOLE. Whew! B. B.: youve done it this time. B. B. What do you mean? WALPOLE. Killed him. The worst case of neglected blood-poisoning I ever saw. It's too late now to do anything. He'd die under the anaesthetic. B. B. [offended] Killed! Really, Walpole, if your monomania were not well known, I should take such an expession very seriously. SIR PATRICK. Come come! When youve both killed as many people as I have in my time youll feel humble enough about it. Come and look at him, Colly. Ridgeon and Sir Patrick go into the inner room. WALPOLE. I apologize, B. B. But it's blood-poisoning.
