“I can’t let you have any more soap to-night,” he told us, when he had finished counting his money. “Fur I hain’t got it ready yet. But I’ll have it fur you early to-morrow mornin’.”

“Do you make it?” quizzed Scoop.

The old man ignored the question.

“Cloudy,” he said, squinting out of the door. “Looks a good bit like rain. Good night, boys. An’ don’t furgit what I told you: This hain’t no [[88]]healthy place fur you to be hangin’ around after dark.”

Hurrying back to the brick house, we excitedly told our chums about our queer adventure in the old mill.

“We’ll separate,” planned Scoop, “and work in pairs. That’ll be the safest. Peg, you and Tom can stay here and guard the house. Jerry and I will watch the mill. And if the spy comes out, we’ll follow him.”

“I’ve had jobs I liked better,” I told him, uneasy.

“Keep the doors locked,” he instructed the house guards. “If we want to get in, we’ll tap on the kitchen window. Like this—see?” and he gave two taps, then one tap, then three taps.

I went with him to the mill, dropping onto my stomach in the weeds just without the mill door. It was good and dark now. But our eyes had become accustomed to the darkness. If the soap man came out of the mill, a moving black shape, we would be sure to see him even if we didn’t hear him.

An hour passed. I was beginning to get stiff.
