When Sarah had left the lounge Dr. Gerard sat where he was for some minutes. Then he walked over to the table, picked up the latest number of Le Matin and strolled with it to a chair a few yards away from the Boynton family. His curiosity was aroused.

He had at first been amused by the English girl's interest in this American family, shrewdly diagnosing that it was inspired by interest in one particular member of the group. But now something out of the ordinary about this family party awakened in him the deeper, more impartial interest of the scientist. He sensed that there was something here of definite psychological interest.

Very discreetly, under the cover of his paper, he took stock of them. First, the boy in whom that attractive English girl took such a decided interest. Yes, thought Gerard, definitely the type to appeal to her temperamentally. Sarah King had strength-she possessed well-balanced nerves, cool wits and a resolute will. Dr. Gerard judged the young man to be sensitive, perceptive, diffident and intensely suggestible. He noted with a physician's eye the obvious fact that the boy was at the moment in a state of high nervous tension. Dr. Gerard wondered why. He was puzzled. Why should a young man whose physical health was obviously good, who was abroad ostensibly enjoying himself, be in such a condition that a nervous breakdown was imminent?

The doctor turned his attention to the other members of the party. The girl with the chestnut hair was obviously Raymond's sister.
