"I don't know," said the policeman, rubbing his head in his
bewilderment.

"How was it done?"

"Oh, don't ask me. All at once there was a clap of thunder, and the
next thing I was on my face in the street."

"Is your comrade inside?"

"Yes; he and M. Sonne and two customers."

"And the _garçon_, wasn't he there?" cried Dupré, with a note of
disappointment in his voice.

The policeman didn't notice the disappointed tone, but answered--

"Oh, the _garçon_, of course."

"Ah," said Dupré, in a satisfied voice, "let us go in, and help them."
Now the people had begun to gather in crowds, but kept at some distance
from the café. "Dynamite! dynamite!" they said, in awed voices among
themselves.

A detachment of police came mysteriously from somewhere. They drove the
crowd still further back.

"What is this man doing here?" asked the Chief.
