"No dawgs allowed in the 'ospital, sir." The scandalised N.C.O. glared at James Henry, who was furiously growling at a hot-air grating in the floor. "You must get 'im out at once, sir: we're being inspected to-day."

"Heel, James, heel. He'll be quite all right, Sergeant. Just find out, will you, about Lady Monica Travers?"

"Beg pardon, sir, but are you a patient?"

"Patient—of course I'm not a patient. Do I look like a patient?"

"Well, sir, there ain't no visiting allowed when the sisters is on duty."

"What? But it's preposterous. Do you mean to say I can't see her unless I'm a patient? Why, man, I've got to go back in an hour."

"Very sorry, sir—but no visiting allowed. Very strict 'ere, and as I says we're full of brass 'ats to-day."

"Derek!" The girl stopped in amazement. "What in the world are you doing here?"
