not remove
his eyes from Perenna. Don Luis remained quite master of himself, but
restless and uneasy at heart.

The door opened. The messenger showed some one in.

It was Florence Levasseur.

CHAPTER SIXTEEN

WEBER TAKES HIS REVENGE

Don Luis was for one moment amazed. Florence Levasseur here! Florence,
whom he had left in the train under Mazeroux's supervision and for whom
it was physically impossible to be back in Paris before eight o'clock in
the evening!

Then, despite his bewilderment, he at once understood. Florence, knowing
that she was being followed, had drawn them after her to the Gare
Saint-Lazare and simply walked through the railway carriage, getting out
on the other platform, while the worthy Mazeroux went on in the train to
keep his eye on the traveller who was not there.

But suddenly the full horror of the situation struck him. Florence was
here to claim the inheritance; and her claim, as he himself had said, was
a proof of the most terrible guilt.

Acting on an irresistible impulse, Don Luis leaped to the girl's side,

question her about the circumstances that brought her here; and I shall
certainly do so."

He released the girl from Don Luis's grasp and made her take a seat. He
himself sat down at his desk; and it was easy to see how great an
impression the girl's presence made upon him. It afforded so to speak an
illustration of Don Luis's argument.

The appearance on the scene of a new person, laying claim to the
inheritance, was undeniably, to any logical mind, the appearance on the
scene of a criminal who herself brought with her the proofs of her
crimes. Don Luis felt this clearly and, from that moment, did not take
his eyes off the Prefect of Police.

Florence looked at them by turns as though the whole thing was the most
insoluble mystery to her. Her
