"Yes," said the dame du comptoir, suavely, "but we have to charge a franc for admission."

Vanderlyn smiled. "It used to be fifty centimes," he said.

"Ah! Monsieur, that was long ago! There are ten times as many provincial papers now as then!"

He put the piece of silver on the counter. As he did so, he heard the door of the shop quietly open, and, with a disagreeable feeling of surprise, he saw the man, the detective he believed he had shaken off, come up unobtrusively to where he was standing.

Vanderlyn hesitated——Then he reminded himself that what he was about to do belonged to the part he had set himself to play: "Well, Madame," he said, "I will go through into your second reading-room and glance over the papers;" he forced himself to add, "I am anxious to find news of a person who has disappeared—who has, I fear, met with an accident."

The detective asked a question of the woman; he spoke in a low voice, but Vanderlyn heard what he said—that is, whether there was any other way out of the two reading-rooms except through the shop. On the woman's replying in the negative, he settled himself down and opened an illustrated paper.

Vanderlyn began systematically going through the provincial papers of the towns at which he knew the train was to stop after he had left it at Dorgival; and after the first uneasy quarter of an hour he forgot the watcher outside, and became absorbed in his task. To his mingled disappointment and relief, he found nothing.

It was of course possible that on the discovery of a dead body in a Paris train, the matter would at once be handed over to the Paris police; that would mean, in this case, that a body so found would be conveyed to the Morgue.

The thought that this might be so made Vanderlyn's heart quail with anguish and horror, and yet, if such a thing were within the bounds of possibility, had he not better go to the Morgue alone and now, rather than later in the company of Tom Pargeter?

As he passed out of the reading-room into the book-shop, and so into the square, he understood for the first time, how it was that he had made so foolish a mistake concerning the detective. The latter at once entered a fiacre which had evidently been waiting for him, and, as Vanderlyn plunged into the labyrinth of narrow streets leading from the Place St. Sulpice to Notre Dame, he could hear the cab crawling slowly behind him.
