ncerned. And did
you do it?"

"How could I? If I only could! If I could find Lupin entangled with a
woman like Ganimard did--well--" said Guerchard between his teeth.

"He'd never get out of YOUR clutches," said the Duke with conviction.

"I think not--I think not," said Guerchard grimly. "But come, I may as
well get on."

He walked across the turf to the foot of the ladder and looked at the
footprints round it. He made but a cursory examination of them, and
took his way down the garden-path, out of the door in the wall into the
space about the house that was building. He was not long examining it,
and he went right through it out into the street on which the house
would face when it was finished. He looked up and down it, and began to
retrace his footsteps.

"I've seen all I want to see out here. We may as well go back to the
house," he said to the Duke.

"I hope you've seen what you expected to see," said the Duke.

"Exactly what I expected to see--exactly," said Guerchard.

"It's Sureau Street," said Guerchard. "But Dieusy has been hunting the
neighbourhood for some one who saw the burglars loading their
conveyance, or saw it waiting to be loaded, for the last hour."

"Good," said M. Formery. "We are getting on."

M. Formery was silent. Guerchard and the Duke sat down and lighted
cigarettes.

"You found plenty of traces," said M. Formery, waving his hand towards
the window.

"Yes; I've found plenty of traces," said Guerchard.

"Of Lupin?" said M. Formery, with a faint sneer.

"No; not of Lupin," said Guerchard.

A smile of warm satisfaction illumined M. Formery's face:

"What did I tell you?" he said. "I'm glad that you've changed your mind
about that."

"I have hardly changed my mind," sa
