secrets for
them, for, on quitting the Rue de Patay, they had immediately turned
to the right, so as to avoid several large excavations, from which a
quantity of brick clay had been dug.
But at last the trail was recovered, and the detectives followed it as
far as the Rue du Chevaleret. Here the footprints abruptly ceased. Lecoq
discovered eight or ten footmarks left by the woman who wore the broad
shoes, but that was all. Hereabout, moreover, the condition of the
ground was not calculated to facilitate an exploration of this nature.
There had been a great deal of passing to and fro in the Rue du
Chevaleret, and not merely was there scarcely any snow left on the
footpaths, but the middle of the street was transformed into a river of
slush.
"Did these people recollect at last that the snow might betray them? Did
they take the middle of the road?" grumbled the young police agent.
Certainly they could not have crossed to a vacant space as they had done
just before, for on the other side of the street extended a long factory
wall.
"Ah!" sighed Father Absinthe, "we have our labor for our pains."
But Lecoq possessed a temperament that refused to acknowledge defeat.
Animated by the cold anger of a man who sees the object which he was
about to seize disappear from before his eyes, he recommenced his
search, and was well repaid for his efforts.
"I understand!" he cried suddenly, "I comprehend--I see!"
Father Absinthe drew near. He did not see nor divine anything! but he no

"Look there," said Lecoq; "what are those marks?"
"Marks left by the wheels of some carriage that plainly turned here."
"Very well, papa, these tracks explain everything. When they reached
this spot, our fugitives saw the light of an approaching cab, which
was returning from the centre of Paris. It was empty, and proved their
salvation. They waited, and when it came nearer they hailed the driver.
No doubt they promised him a handsome fare; this is indeed evident,
since he consented to go back again. He turned round here; they got into
the vehicle, and that is why the footprints go no further."
This explanation did not please Lecoq's companion. "Have we made any
great progress now that we know that?" he asked.
Lecoq could not restrain an impulse to shrug his shoulders. "Did you
expect that the tracks made by the fugitives would lead us through Paris
and up to their very doors?" he asked.
"No;
