The Lieutenant he inspects some of 'em, lookin' wise; and then he walks to the back, where there's a high board fence with barbed wire on top. "What's over there?" says he.

"Blamed if I know," says I.

"It's rather important," says he. "Let's have a look."

I didn't get the connection, but I helped him shove a packin'-case up against the fence, so he could climb up. For a minute or so he stares, then he ducks down and beckons to me.

"I say," he whispers. "Come up here. Don't show your head. There! What do you make of that?"

So I'm prepared for something tragic and thrillin'. But all I can see is an old slate-roofed house, one of these weather-beaten, dormer-windowed relics of the time when that part of town was still in the suburbs. There's quite a big yard in the back, with a few scrubby old pear trees, a double row of mangy box-bushes, and other traces of what must have been a garden.

In the far corner is a crazy old summer-house with a saggin' roof and the sides covered with tar paper. There's a door to it, fastened with a big red padlock.

Standin' on the back porch of the house are two of the help, so I judged. One is a square-built female with a stupid, heavy face, while the other is a tall, skinny old girl with narrow-set eyes and a sharp nose.

"Well," says I, "where's your riot?"

"S-s-s-sh!" says he. "They're up to some mischief. One of them is hiding something under her shawl. Watch."
