It seemed a long time before the ambulance, which Larry summoned, made its arrival, but it was only a few minutes ere it clanged up to the pier, the crowd parting to let it pass. In an instant the white-suited surgeon had leaped out of the back of the vehicle before it had stopped, and was kneeling beside Retto.

With deft fingers he felt of the wound on the man's head.

"Possible fracture," he said in a low voice. "Double one of the leg, I'm afraid," as he glanced at that member. "Lend a hand, boys, and we'll get him on the stretcher."

There were willing enough helpers, and Retto

was soon in the ambulance and on the way to the hospital, the doctor clinging to the back of the swaying vehicle as it dashed through the streets, with the right of way over everything on wheels.

"Here's news in bunches," thought Larry, as he saw the ambulance disappearing around a corner. "I must telephone this in, and I guess it will be a beat. To think that after all that I have Retto where I want him. I'm sorry, of course, that he's hurt, but I guess he can't get out of the hospital very soon. I'll have a chance to question him. Then I'll make him tell me where Mr. Potter is, and that will end my special assignment. I'll not be sorry, either. It's been a hard one, though I'm glad I got it, for the experience is fine."

Thus musing Larry looked for a telephone station and soon the story of Retto's accident was being sent over the wire to the city editor.

"This will make a fine lead for our Potter story," said Larry, as he finished telling of the accident.

"I've got another plan," said Mr. Emberg.

"What is it?"
