"I would not care to hazard a definite opinion on so cursory an observation," returned the other, in a dry, reticent, ultra-professional manner. "But I will go so far as to say that I do not think it is a case of shell-shock. If it is what I suspect, that first attack was the precursor of another, possibly a worse attack. Ha! it is commencing. Look at his thumb—that is the danger signal!"
Colwyn looked across the room again. The young man was still sitting in the same posture, with his gaze bent on the open sea. His left hand was extended rigidly on the table in front of him, with the thumb, extended at right angles, oscillating rapidly in a peculiar manner.
"This attack may pass away like the other, but if he looks round at anybody, and makes the slightest move, we must secure him immediately," said Colwyn's companion, speaking in a whisper.
He had barely finished speaking when the young man turned his head from the open window and fixed his blue eyes vacantly on the table nearest him, where an elderly clergyman, a golfing friend, and their wives, were breakfasting together. With a swift movement the young man got up, and started to walk towards this table.
Colwyn, who was watching every movement of the young man closely, could not determine, then or afterwards, whether he meditated an attack on the occupants of the next table, or merely intended to leave the breakfast room. The clergyman's table was directly in front of the alcove and in a line with the pair of swinging glass doors which were the only exit from the breakfast-room. But Colwyn's companion did not wait for the matter to be put to the test. At the first movement of the young man he sprang to his feet and, without waiting to see whether Colwyn was following him, raced across the room and caught the young man by the arm while he was yet some feet away from the clergyman's table. The young man struggled desperately in his grasp for some moments, then suddenly collapsed and fell inert in the other's arms. Colwyn walked over to the spot in time to see his portly companion lay the young man down on the carpet and bend over to loosen his collar.
The young man lay apparently unconscious on the floor, breathing stertorously, with convulsed features and closed eyes. After the lapse of some minutes he opened his eyes, glanced listlessly at the circle of frightened people who had gathered around him, and feebly endeavoured to sit up. Colwyn's companion, who was bending over him feeling his heart, helped him to a sitting posture, and then, glancing at the faces crowded around, exclaimed in a sharp voice:
"He wants air. Please move back there a little."
"Certainly, Sir Henry." It was a stout man in a check golfing suit who spoke. "But the ladies are very anxious to know if it is anything serious."
"No, no. He will be quite all right directly. Just fall back, and give him more air. Here, you!"—this to one of the gaping waiters—"just slip across to the office and find out the number of this gentleman's room."
The waiter hurried away and speedily returned with the proprietor of the hotel, a little man in check trousers and a frock coat, with a bald head and an anxious, yet resigned eye which was obviously prepared for the worst. His demeanour was that of a man who, already overloaded by misfortune, was bracing his sinews to bear the last straw. As he approached the group near the alcove table he smoothed his harassed features into an expression of solicitude, and, addressing himself to the man who was supporting the young man on the floor, said, in a voice intended to be sympathetic,
