Quite as much time was devoted by Dr. Osterhout in the days immediately following to covering the devious trail of his patient as to treating her medically. After a consultation with Mrs. Barham, in which each solemnly pretended that the other entertained no suspicion of Mona's slip, he wrote a heedfully worded letter of misinformation and assurance to Ralph Fentriss, explaining that his wife had been taken to the hospital after a mild attack, more for rest than anything else; that no member of the family was to come over, and that she would be in condition to return home in a few days. This latter was true, for Mona's recuperative powers were great. None of the family came. But to Osterhout's surprise, he ran upon Patricia while walking down Broad Street on Sunday. She was with a pretty and smartly dressed girl a little older than herself.

"What are you doing here, Pat?" he demanded.

"Week-ending with Cissie Parmenter." With an aplomb amusing in one so young she indicated her companion. "She's my b.f. at school. Cissie, this is Dr. Bobs. You know about him."

"Yes, indeed. How d'you do, Dr. Osterhout."

"And what manner of creature is a b.f.?" asked he quizzically, taking the extended hand which was ornamented with a valuable ruby.

"Best friend, of course, stupid Bobs," returned Pat. "What kind of a bat are you on down here?"

"Your mother's been ill. She's in hospital here," he answered and immediately wondered whether he had not spoken unwisely.

"Hospital?" Pat opened wide eyes. "Is it dangerous?"

"No. She's coming along very well."

"Take me to see her." She turned to Cissie. "I'm plunged, Ciss, but the luncheon's off for me. Tell the boys. You may have my c.t. See you this afternoon."
