fellow fell back dead.

"How unfortunate!" cried the commissary, "to die just when he would
have told us all. These few words will scarcely suffice to identify
the murderers. Can any one help us?"

M. Bontoux looked round.

"The name he mentioned I know," said the night-porter, quickly. "This
M. Gascoigne came here frequently. He is an Englishman."

"So I gathered from the dead man's words. Do you know his domicile in
Paris?"

"Rue St. Honoré, Hôtel Versailles and St. Cloud. I have seen him enter
it more than once, with his wife. He has lived there some months."

"We must, if possible, lay hands on him at once. You, Jules, hasten
with another police-agent to the Rue St. Honoré; he may have gone
straight to his hotel."

"And if we find him?"

"Arrest him and take him straight to the Préfecture. I will follow.
There, there! lose no time."

"I am already gone," said the police-officer as he ran downstairs.
