"I--I guess it was the baboon," answered Teddy whimsically.

"Or else, maybe, it was the b.u.mp I got when I hit the deck of the 'Fat Marie.'"

Phil came up and joined them at that moment, waiting for his turn to go on in his trapeze act for the evening performance.

Mr. Sparling surveyed him keenly. He noted the trim, athletic figure, the poise of the head and the steady clear eyes that held one irresistibly.

"You are looking very handsome tonight, Phil," said the owner.

"Thank you, sir. 'Handsome is as handsome does,' as the saying goes," laughed the Circus Boy. "Are you having the net watched, Mr. Sparling?"

"Yes, my lad. Two men are keeping close tab on the big spider web all the time, except in the afternoon, when no one would dare to tamper with it for fear of being detected."

"I am not so sure of that. You see, I have a personal interest in that net, seeing that I have to risk my bones over it twice each day."

"Don't worry. It will be well watched, Phil."

"I take the first drop in it, you know, so if it should give way you would be minus Phil Forrest."

"Teddy tells me you and he are thinking of buying out the Sparling shows, eh?"

"Why, Teddy, how could you say such a thing?" demanded Phil, reddening.

Teddy expostulated, explaining that it was merely a dream in his own mind, repeating that Phil knew nothing of it.

"I do intend to own a show, as I have told you before, Mr. Sparling, as soon as I have enough money. I am afraid, however, that that day is a long way off."

"Perhaps not so far off as you think, Phil. Perhaps both of you may own a show much sooner than you even dream," said the showman, significantly. "Well, good night, boys if I do not see you again."

"What do you think he meant by that?" questioned Teddy.

"I am sure I do not know. Perhaps he thinks we have a future before us and that we shall make rapid advances. I hope so, don't you, Teddy?"

"I think I would rather find my egg than have most anything else just now."

"Oh, hang your egg! There goes my cue. I must get out, now.

Bye, bye. You are a lucky boy not to have to work on this hot night."

Phil waved his hand and tripped out into the arena. A few minutes later he was soaring through the air with the gracefulness and ease of a bird on the wing.

The boys did not meet again until bedtime, for Phil had turned in immediately upon reaching the boat. Teddy, of course, was the last one to go to bed, but he was soon asleep after reaching there.

Phil, on the contrary, had lain awake for some hours, thinking.

He was still seeking a solution to the mystery that had been disturbing them almost from the beginning of the season.

Twice had an effort been made to do him serious injury at least.

Who could have taken so violent a dislike to him as to wish to cause his death? There seemed to be no answer to the question.

"I can think of no one, unless it is Diaz," muttered the boy.

"Yet he surely was not one of those who were plotting out on the lot that night. He would not have had time to get back to the boat ahead of me. Then again, Teddy was sure that the clown had been back for more than an hour. He may have had something to do with laying the trap in the ring for Dimples and myself."

"I am afraid I am not on the right track at all," decided Phil at last, with a deep sigh.

He was still awake when the "Fat Marie" shook off her moorings and with a long blast of her siren, drifted out into the stream and began pounding down the river.

Phil got up, stretched himself, looked out of the window, then decided to go on deck to get the breeze, for the heat was stifling in his stateroom. Teddy was sound asleep.

The deck seemed to be deserted. Phil walked over to the rail and leaning both elbows upon it closed his eyes dreamily.

It must have been fully an hour later when Teddy awakened suddenly, with a foreboding that something was not as it should be.

"Phil!" he called.

There was no reply.

"_Phil!_" repeated Teddy in a louder tone.

Failing to get a response, Teddy arose and found his companion's bed empty. Teddy, knowing that Phil seldom ever left the stateroom after retiring, decided to go out to look for him.

He investigated the cabin, then going out on dock peered into every shadow, calling softly for Phil.

Failing to get any trace of his chum, Teddy returned to his cabin, put on his slippers and went down to the lower deck, where he made inquiries of the watchman, but with no better success.

Teddy Tucker began to feel alarmed. He hurried to the upper deck again, once more going over it carefully, as well as the inside of the boat.

A terrible suspicion began to force itself upon him.

"Man overboard!" bellowed the Circus Boy. "Man overboard!"

He ran through the corridors shouting the startling cry, then out to the deck repeating it as he ran.

The cry was taken up by others as they rushed from their cabins, Mr. Sparling among the number.

"Where, where?" shouted the showman. "Who--who--"

"It's Phil! He's gone. He's over there, somewhere, I don't know where!"

CHAPTER XXII

OVERBOARD INTO THE RIVER

"I can't understand it," Phil mused, as the soft evening breezes lulled him into slumber.

"What! What!" he cried suddenly. "What is it? I'm falling!"

The deck of the "Marie" all at once seemed to have dropped from beneath him. He felt himself falling through s.p.a.ce. What could it mean?

With the showman's instinct the Circus Boy quickly turned his body, spread out his hands and righted himself.

The night was black, and as yet he had not succeeded in collecting his senses sufficiently to decide what had happened.

He knew that he was falling, but that was all.
