"Why, what nonsense!" snapped the Senior Surgeon. "What—!"

"And the Portuguese woman the week before that," interrupted Rae
Malgregor dully.

"Stuff and nonsense!" said the Senior Surgeon. "It's nothing but coincidence! Pure coincidence! It might have happened to anybody!"

"And she hasn't slept for almost a fortnight." the Superintendent confided, "nor touched a drop of food or drink, as far as I can make out, except just black coffee. I've been expecting this break-down for some days."

"And-the-young-drug-store-clerk-the-week-before-that," Rae Malgregor resumed with sing-song monotony.

Brusquely the Senior Surgeon stepped forward and taking the girl by her shoulders, jerked her sharply round to the light, and, with firm, authoritative fingers, rolled one of her eyelids deftly back from its inordinately dilated pupil. Equally brusquely he turned away again.

"Nothing but moonshine!" he muttered. "Nothing in the world but too much coffee dope taken on an empty stomach,—'empty brain,' I'd better have said! When will you girls ever learn any sense?" With searchlight shrewdness his eyes flashed back for an instant over the haggard gray lines that slashed along the corners of her quivering, childish mouth. A bit temperishly he began to put on his gloves. "Next time you set out to have a 'brain-storm,' Miss Malgregor," he suggested satirically, "try to have it about something more sensible than imagining that anybody is trying to hold you personally responsible for the existence of death in the world. Bah!" he ejaculated fiercely. "If you are going to fuss like this over cases hopelessly moribund from the start, what in thunder are you going to do some fine day when out of a perfectly clear and clean sky Security itself turns septic and you lose the President of the United States—or a mother of nine children—with a hang-nail?"

"But I wasn't fussing, sir!" protested Rae Malgregor with a timid sort of dignity. "Why, it never had occurred to me for a moment that anybody blamed me for—anything!" Just from sheer astonishment her hands took a new clutch into the torn flapping corner of the motto that she still clung desperately to even at this moment.

"For Heaven's sake stop crackling that brown paper!" stormed the Senior
Surgeon.

"But I wasn't crackling the brown paper, sir! It's crackling itself," persisted Rae Malgregor very softly. The great blue eyes that lifted to his were brimming full of misery. "Oh, can't I make you understand, sir?" she stammered. Appealingly she turned to the Superintendent. "Oh, can't I make anybody understand? All I was trying to say,—all I was trying to explain, was—that I don't want to be a trained nurse—after all!"
