"Don't move these things," directed M. Pougeot. "It's possible some one will call for them, and if anyone should call, why—that's Gibelin's affair. Now we'll see these Americans."

It was a quarter past ten, and the hilarity of proceedings at the Fourth-of-July banquet (no ladies present) had reached its height. A very French-looking student from Bridgeport, Connecticut, had just started an uproarious rendering of "My Bonnie Lies Over the Ocean," with Latin-Quarter variations, when there came a sudden hush and a turning of heads toward the half-open door, through which a voice was heard in peremptory command. Something had happened, something serious, if one could judge by the face of François, the head waiter, who stood at the corridor entrance.

"Not so fast," he insisted, holding the young men back, and a moment later there entered a florid-faced man with authoritative mien, closely followed by two policemen.

"Horns of a purple cow!" muttered the Bridgeport art student, who loved eccentric oaths. "The house is pulled!"

"Gentlemen," began M. Pougeot, while the company listened in startled silence, "I am sorry to interrupt this pleasant gathering, especially as I understand that you are celebrating your national holiday; unfortunately, I have a duty to perform that admits of no delay. While you have been feasting and singing, as becomes your age and the occasion, an act of violence has taken place within the sound of your voices—I may say under cover of your voices."

He paused and swept his eyes in keen scrutiny over the faces before him, as if trying to read in one or the other of them the answer to some question not yet asked.

"My friends," he continued, and now his look became almost menacing, "I am here as an officer of the law because I have reason to believe that a guest at this banquet is connected with a crime committed in this restaurant within the last hour or two."

So extraordinary was this accusation and so utterly unexpected that for some moments no one spoke. Then, after the first dismay, came indignant protests; this man had a nerve to break in on a gathering of American citizens with a fairy tale like that!

"Silence!" rang out the commissary's voice sharply. "Who sat there?" He pointed to a vacant seat at the long central table.

All eyes turned to this empty chair, and heads came together in excited whispers.
