'Darwin,' suggested Alix intelligently. 'Galileo. Sir Isaac Newton. Sir Oliver Lodge. Lots more.'

'Well, let's try this passage.'

They tried it. It led them on and on. It looked wrong, but might be right, in such a strange world as a hospital, where anything may be right or wrong and you never know till you try.

They saw at last ahead of them a closed door—not a glass door but a baize one. From behind it screaming came, wild, shrill, desperate, as if some one was being hurt to death.

'O Lord!' said Nonie, 'it's the theatre. Look, it's written on the door. Come away quick. There must be an operation on.'

Beyond the door there was a shuffling and scuffling; it was pushed open, and two figures muffled in white, like the stretcher-women, dragged out a Red Cross girl in a faint.

'Fetch her some water,' said one. 'Idiot, why didn't she come out before she went off? These Red Cross girls—All right, she 's coming round.... I say, you know, you mustn't do that again. People are supposed to come out of the theatre before they faint, not after. It's an awful crime.... Is it your first operation? Well, it was silly of them to send you down to such a bad one. I expect the screaming upset you. She didn't feel anything, you know.... Here, drink this. You're all right now, aren't you? I must get back. You'd better go up to your ward and ask your Sister if you can lie down for a bit.'

Alix and Nonie had retreated down the passage.

'What a place,' Alix was muttering savagely. 'Oh, what a place.'

They came out on a different staircase; fleeing down it they were in a corridor, long and unhappy and full of hurrying housesurgeons and nurses and patients' friends (for it was visiting-hour).
