she would speak.

Would she be believed?

This was the decisive question, and from what he had heard of her, it
seemed that she would be.

Denials would not suffice. He did not go to Caffie's at a quarter past
five. Where was he at this moment? What witness could he call upon?
Caffie's wound was made by a hand skilled in killing, and this learned
hand was his, more even than that of a murderer. Every one knew that his
position at that moment was desperate, financially speaking; and,
suddenly, he paid his debts. Who would believe the Monte Carlo story?

One word, one little hint, from this Madame Dammauville and he was lost,
without defence, without possible struggles.

Truly, and fortunately, since she was paralyzed and confined to her bed,
he ran no risk of meeting her face to face at the corner of a street, or
at the house of an acquaintance, nor of hearing the cry of surprise that
she would not fail to give on recognizing him. But that was not enough
to make him sleep in an imprudent security on saying to himself that this
meeting was improbable. It was improbable, also, to admit that some one
was exactly opposite to Caffies window at the moment when he drew the
curtains; more improbable yet to believe that this fact, insignificant in
itself, that this vision, lasting only an instant, would be so solidly
engraved in a woman's memory as to be distinctly remembered after several
months, as if it dated from the previous evening; and yet, of all these
improbabilities, there was formed a reality which enclosed him in such a
way that at any moment it might stifle him.
