A man breathless from haste appeared in the doorway of the anteroom.

"Dr. Harpe——"

"What is it?" She did not turn around.

"A case came in at the hospital—feller shot, down the street."

"Where's Lamb?" she demanded irritably.

"Out of town."

"Thunder!" She stamped her foot impatiently. "Who is it?" she scowled.

"Billy Duncan. He's bleedin' bad, Doc." There was a note of entreaty in his voice.

"All right," she answered shortly, "I'll be down."

"Frien' of yours?" inquired Terriberry.
