Who was this mysterious individual who had called Elizabeth twice over the telephone, and then, no sooner put into communication with her, had refused to talk to her?

Fandor felt nervous, anxious, exasperated by this incident; but it would never do to trouble his young friend to no good purpose. He led her back to the garden.

“Where were we in our talk, monsieur?” asked Elizabeth.

With a considerable effort, the journalist collected his thoughts.

“We were discussing the mysterious paper found at your brother’s, mademoiselle.”

In agreement with Elizabeth, Jérôme Fandor determined the approximate size of this list of addresses. He tore from his note-book a sheet of white paper.

Elizabeth looked fixedly at the white sheet for a long time, as though, by concentrated will power, she could force the mysterious names which she read some days before on the original paper, to rise up in front of her eyes. Certainly it seemed to her that on this list figured the name of her brother, that of the Baroness de Vibray, lawyer Gérin’s also: then she remembered a double name, a name not unknown to her, which had appeared in the list.

“Barbey-Nanteuil!” she suddenly cried. “Yes, I do believe those two names were on it!”

Fandor smiled. Encouraged by her smile and the results of this semi-clairvoyant attempt, Elizabeth allowed her thoughts free play.

“I am sure of it: there was even a mistake in spelling: Nanteuil was spelled Nanteuil: the bankers were third or fourth on the list, and I am certain now that the Baroness de Vibray’s name headed the list. There was also a date, composed of two figures – a 1... then – wait a minute!... a figure with a tail to it... that is to say, it could only have been a 5, a 7, or a 9... I cannot remember which. Then there were other names I had never heard of.”

“Try, mademoiselle, to remember.”

There was a silence. Fandor was puzzling over the figures he had written down in the order Elizabeth had mentioned them – fifteen – seventeen – nineteen – but what could he deduce from them?... Ah! The mysterious robbery of rue du Quatre Septembre was committed on May 15th!

There may be a clue there! The thread of Fandor’s reflections were abruptly broken by a cry from Elizabeth.

“I have recalled a name – something like...

Thomas!... Does that tell you anything?”

“Thomas?” repeated Jérôme Fandor slowly. “I don’t see...”

But suddenly he saw light!

He jumped up:

“Isn’t it Thomery?” cried he, intensely excited. “Are you not confounding Thomas with Thomery?” Elizabeth, taken aback, confused, tried hard to remember: she threshed her memory with knitted brows.
