"Which the police and I will keep!" interrupted Mr. Watson.

"Perhaps that would be better," agreed Mr. Mandell.

So the plot for the downfall of Shalleg was laid. It appeared that he had come back to St. Louis, and, by dint of careful watching, and by his knowledge of the game, he had managed to steal the signal system used between the Cardinal pitchers and catchers. This he proposed disclosing to the Chicago team, but of course the manager would have nothing to do with the scheme.

Shalleg had named a low resort for the transfer of the information he possessed, he to receive in exchange a sum of money. He was in desperate straits, it appeared.

The Cubs' manager, Joe and Mr. Watson, with a detective, went to the appointed meeting place. The manager went in alone, but the others were hiding, in readiness to enter at a signal.

"Did you bring the money?" asked Shalleg, eagerly, as he saw the man with whom he hoped to make a criminal "deal."

"I have the money, yes," was the cool answer. "Are you prepared to disclose to me the Cardinal battery signals?"

"Yes, but don't speak so loud, someone might hear you!" whined Shalleg.

"That's just what I want!" cried the manager in loud tones, and that was the signal for the officer to come in. He, Joe and Mr. Watson had heard enough to convict Shalleg.

"Ha! A trap!" cried the released player, as he saw them close in on him. He made a dash to get away, but, after a brief struggle, the detective overpowered him, for Shalleg's manner of life was not such as to make him a fighter.
