"Help! Help!" he shouted loudly. "Mademoiselle has been shot from
outside! _Help!_"

In a few seconds the elderly manservant burst into the room in a state
of intense excitement.

"Quick!" cried Hugh. "Telephone for a doctor at once. I fear your
mistress is dying!"

Henfrey had placed his hand upon Mademoiselle's heart, but could detect
no movement. While the servant dashed to the telephone, he listened
for her breathing, but could hear nothing. From the wall he tore down
a small circular mirror and held it against her mouth. There was no
clouding.

There was every apparent sign that the small blue wound had proved
fatal.

"Inform the police also!" Hugh shouted to the elderly Italian who was at
the telephone in the adjoining room. "The murderer must be found!"

By this time four female servants had entered the room where their
mistress was lying huddled and motionless. All of them were in

firing, had, no doubt, slipped along, and out of the gate.

But why had Mademoiselle been shot just at the moment when she was about
to reveal the secret of his lamented father's death?

He descended to the garden, where he examined the bushes which cast
their dark shadows. But all was silence. The assassin had escaped!

Then he hurried out into the road, but again all was silence. The only
hope of discovering the identity of the criminal was by means of the
police vigilance. Truth to tell, however, the police of Monte Carlo are
never over anxious to arrest a criminal, because Monte Carlo attracts
the higher criminal class of both sexes from all over Europe. If the
police of the Principality were constantly making arrests it would be
bad advertisement for the Rooms. Hence, though the Monte Carlo police
are extremely vigilant and an expert body of officers, they pre
