At that moment there came a knock on the door leading to the hall. One of the members of the club opened it, and six men, wearing the white uniforms of caterer’s men, walked in, bearing great baskets covered with white cloths.

“A surprise!” cried half a dozen voices.

“A feed!” said Bernice, with a laugh.

“Who is responsible for this?” asked the chief.

The baskets were placed in the centre of the stage, and the members of the company gathered about them.

Nick and Patsy stood back where the men who had brought the baskets could see every move they made.

Then, when the entire company was bending over the baskets, Nick gave a signal and seized the chief of the Great Diamond Syndicate!

There were screams, calls for help, and frantic efforts at escape, but in a moment every member of the club who belonged to the villainous diamond syndicate was securely handcuffed.

“How was that for a spread?” asked Chick, who had seized Anton.

“What does it mean?” demanded the chief, looking hard at Nick, still wearing the stage costume prepared for Mantelle.
