red to you."

"You keep watch," said Markby, hurriedly; "and be ready for any
emergency. It is a bold stroke we are playing for. Lenoir is a
desperate ruffian, and the least mistake in the business would be
something which I for one don't care to contemplate."

"Lenoir be blowed," replied the man in the blouse; "the only people I
care about if we should go and make a mess of the job is, firstly--Jack
Harkaway, and secondly, his pal Harry Girdwood, which a harder fist
than his I have seldom received on my unlucky snuffer-tray."

And he was gone.

CHAPTER XCI.

MARKBY'S NEXT STEP--THE PREFECT OF POLICE--THE PLOT THICKENS--A GLIMPSE
OF MARKBY'S PURPOSE--A DOUBLE TRAITOR--DEADLY PERIL.

Markby went off muttering to himself.

"Wish that scamp could only share the fate I have reserved for that

"It is a very important matter," said the prefect, "that I will not
attempt to disguise from you. This Lenoir is evidently at the head of a
gigantic conspiracy. We have been long seeking to discover how he
disposed of his counter----"

"Stock," said Markby, interrupting the prefect, with a smile. "He is
the quintessence of caution, sir, and he never alludes to it by any
other term."

"You really think that these English people are their confidants?"

"The chief confederates; yes. They are the heads of the English part of
our scheme."

"How many men should you require?" demanded the prefect, changing the
subject abruptly.

"A dozen fully armed, in plain clothes. These can descend into the
_caveaux_ to make the capture."

"A dozen!"

"Yes."

"So many!"

"You don't know Lenoir," said Markby; "he's the very devil when he's
aroused. A dozen will have all their work to do. As for the two
