check. "Still, the voice described as metallic seems to have been Mr.
Saffron's; at a certain moment at least. As a merely medical question of
some interest, I wonder if such a symptom or sign of--er--irritability
could be intermittent, coming and going with the--er--fits! Irechester
didn't say anything on that point. Have you any opinion?"

"None. I don't know. I should like to ask Dr. Irechester." Then, with a
sudden smile, she amended, "No, I shouldn't!"

"And why not, pray? Professional etiquette?"

"No, pride. Dr. Irechester laughed at me. I think I see why now; and
perhaps why Mr. Beaumaroy--" She broke off abruptly, the slightest
gesture of her hand warning Naylor also to be silent.

Having said good-bye to his friends by the window, Beaumaroy was
sauntering across the room to pay the like courtesy to herself and
Naylor. Mary rose to her feet; there was an air of decision about her,
and she addressed Beaumaroy almost before he was within speaking distance
as it is generally reckoned in society.

"If you're going home, Mr. Beaumaroy, shall we walk together? It's time I
was off, too."

Beaumaroy looked a little surprised, but undoubtedly pleased. "Well, now,
what a delightful way of prolonging a delightful visit. I'm truly
grateful, Dr. Arkroyd."

"Oh, you needn't be!" said Mary with a little toss of her head.
