He lay his cards on the table, and he had the two, three, four, five and six of hearts.

There was a shout of astonishment.

"Ze pot ees mine!" exultantly cried the Frenchman.

"Stop!" rang out Frank Merriwell's clear voice. "That pot is not yours!"

Everyone looked at Merry.

"He is using a table 'hold-out!'" accused Frank, pointing straight at Montfort. "I saw him make the shift. The five cards that really belong in his hands will be found in the hold-out under the table!"

There was dead silence. The Frenchman turned sallow.

"It makes no difference," said the quiet voice of the detective, breaking the silence. "I have a higher straight flush of clubs here. Mine runs up to the eight spot, and so I win the pot."

He showed his cards and raked in the pot.

With a savage cry, M. Montfort flung his hand aside, leaped to his feet, sprang at Frank, and struck for Merry's face.
