"Her room is at the top of the house," said the inspector. "The bed
had been slept in, but she does not appear to have taken away any of
her clothes."

"Extraordinary! This is beginning to look a very complicated
business," said M. Formery gravely.

"Perhaps Guerchard will be able to throw a little more light on it,"
said the Duke.

M. Formery frowned and said, "Yes, yes. Guerchard is a good
assistant in a business like this. A little visionary, a little
fanciful--wrong-headed, in fact; but, after all, he IS Guerchard.
Only, since Lupin is his bugbear, he's bound to find some means of
muddling us up with that wretched animal. You're going to see Lupin
mixed up with all this to a dead certainty, your Grace."

The Duke looked at the signatures on the wall. "It seems to me that
he is pretty well mixed up with it already," he said quietly.

"Believe me, your Grace, in a criminal affair it is, above all
things, necessary to distrust appearances. I am growing more and
more confident that some ordinary burglars have committed this crime
and are trying to put us off the scent by diverting our attention to
Lupin."

The Duke stooped down carelessly and picked up a book which had
fallen from a table.
