Mr. Colliver took the suggestion sourly.

"Everybody in Troy knows me," he replied with dignity.

"Exactly," the theologian answered. "But Troy is not on the ship's passenger lists to any such extent as to corroborate your statement. There may be Harvard men on board who know me by name but for all they know I may be made up to represent Professor Sedgely so as to gain your confidence and rob you."

"My collars encircle the necks of more men than those of any other maker," said Colliver quoting one of his advertisements. "My name is known everywhere. No man is perfectly dressed without my collars. I presented a swimming pool to Troy and there isn't a man or woman in the city but would resent any slur on me."

"My dear sir," said the professor smiling, "I am not attacking your good name or your city's fame. I am only saying that if you were crossing with the idea of making a killing at games of chance I should not benefit because you assumed the name of one who ornaments the cervical vertebræ of perfectly dressed men. I only meant that anything can take place on a ship such as this is and that this man who escaped tonight may have done so to avoid capture and possible imprisonment or even death."

"The purser had a wireless sent to the company's office and no doubt has a reply by this time," another passenger broke in.

"He is probably in prison now," Professor Sedgely remarked.

"You certainly have a cheerful mind," Colliver commented.

"I read for mental relaxation the lightest forms of fiction," the professor answered, "and I am prepared for anything. I maintain that every passenger on a fast ship like this is regarded as a possible victim by the cleverest criminals in existence. For myself I have nothing of value, being poorly paid, but our friend there who has so finely benefitted his home city wears a diamond pin of great value. Furthermore there is a sapphire set in platinum on his finger which might well tempt the professional robber."

"Say," said Colliver a little uneasily, "you're observant all right. Anything else you saw?"
