“‘Prince,’ you—you’ll pitch for us next Saturday?” There was pleading in Meggy’s tone. “We need you badly. You—you just can’t fail.”

A shadow passed over the strange dark face. “I—I’ll try to be there,” the “Prince” replied. “And now,” he said abruptly, “I must bid you goodnight. I am working on something for the Colonel, some—something rather large for so unimportant a person as myself.”

“Thank you, ‘Prince.’” Meggy made for the door. “Thank, oh thank you,” came from the others.

Johnny was the last one out. Just why he should have looked back at the instant the door was swinging shut behind him, he could never tell. Enough that he did look back and that, from this looking through a crack not more than two inches wide, he received the shock of his young life.

He saw a leg, the leg of the “Prince.” His sock had slipped down. He was pulling it up. In doing so, he lifted his trouser leg so high that it showed his bared leg. And that leg was not brown, but white as Johnny’s own.

“He’s not naturally brown!” The thought shot through the boy’s mind like a flash. “His hands, arms and face are dyed; probably his hair is too. I wonder why?” He was to continue wondering for some time to come.

CHAPTER XVI
A TENSE MOMENT

When a mysterious stranger takes up his abode in any community, there is sure to be a difference of opinion regarding his true nature. To some he is certain to be a romantic figure, to others an evil menace. It was so with the “Prince.” There were those who said he was a famous young chemist working out a formula that was to be of vast benefit to all the world. There were others—and this was strange—many others who said, “He is an industrial spy! Colonel Chamberlain will find this out too late!”

But what is an industrial spy? Probably there was not one person in ten who could have told. And always the thing we do not understand is the one we fear most.

Having heard all this, Johnny, on the day following his visit to the “Prince,” buckled up his courage and walked into Colonel Chamberlain’s office.
