But after the attack four persons were in the laboratory! I can't make it out!" "The robbery," said the reporter, "could only have been committed before the attack upon Mademoiselle Stangerson in her room.

"It is quite possible, Monsieur, as this proves." And the young rascal drew a copy of the "Epoque" from his pocket, dated the 21st of October (I recall the fact that the crime was committed on the night between the 24th and 25th), and showing us an advertisement, he read: "'Yesterday a black satin reticule was lost in the Grands Magasins de la Louvre.

It contained, amongst other things, a small key with a brass head.

A handsome reward will be given to the person who has found it.
This person must write, poste restante, bureau 40, to this address: M.
