Cherche-Midi prison,
our detective had learned that Vagualame-Fantomas was in the habit of
visiting a mysterious house in rue Monge. Here he met many of his
accomplices. It was here the band of spies and traitors, of which he
seemed chief, disguised themselves, issuing forth to ply their
nefarious trade and mock the police.

Juve made a compact with himself.

"As soon as I have handed my corporal over to the military jailors, I
know where I shall go to smoke a cigarette!"

WILHELMINE'S SECRET

"You are alone, Wilhelmine?"

Mademoiselle de Naarboveck had just left the house in the rue Fabert.
It was three in the afternoon, and she was going shopping. At the
corner of the rue de l'Universite she came on Henri de Loubersac.

It was a delightful surprise. She had not seen him for several days.

frequently sudden, you know!"

"And Mademoiselle Berthe?"

Wilhelmine raised her beautiful bright eyes and met her fiance's

"I was going to do a little shopping ... nothing much ... there is no
sort of hurry!"

She felt that Henri wished to discuss something important with her:
hers was too direct a nature to put him off with flimsy excuses when
he desired a serious talk.

"Should we walk on a little, talking as we go?" she suggested, with a
charming smile. To walk and talk with Henri was such a ple
