And that meant that Mr. Gagnon would shortly be in the hands of a squad of G-men and that that same squad would make a net about Porpoise Island, by land and sea, ready for the big showdown on Thursday next!

“I’m hungry, Stan,” confessed John, as they started back for the yacht. “What I mean is—I’m actually HUNGRY!”

Stan didn’t seem surprised.

CHAPTER XIII
Hegarty Plans a Surprise

IT WAS a tired and hungry duet of detectives who walked down the rickety old wharf about midnight and climbed aboard the good sloop Water Witch now masquerading as a Marconi sloop called Staghound! Not too tired, however, for John to go right to the stove and light the burners. He had hot coffee ready while he discussed the evening’s events with Stan.

“Stuffed alligator skins,” said John. “Gagnon was one scared man.”

“Tried to yell for help when Dago and Dad came down to the cove, though,” said Stan. “Figured he might be better off with his old pals!”

“Where will they take him now, Stan, I wonder?”

“For one thing, the newspapers won’t hear about the capture of Gagnon, I bet. Dad and the F. B. I. had a tough time keeping it secret that my father was a G-man in the Hogan case. If they hadn’t succeeded, everyone would know that Dad was a Special Agent and it would have spoiled his future work. The day gangland gets his photo to compare with the G-man who broke the Hogan case they’ll get Dad on a spot, I’m afraid.”

“Guess you’re right. I remember, speaking of Gagnon again, that they spirited Racira away in the Hogan affair, and I guess the mobsters will be astonished when he appears in court as a witness against them!”
