"Yes, sah, Colonel!"

"You stay here until I come back. I'm going out, and I don't know what
time I'll be in. Be careful to get straight any messages that come in
over the wire, and if Jack Young calls up get the 'phone number of the
place where he is so I can call him."

"Yes, sah, Colonel."

"And, Shag!"

"Yes, sah, Colonel!"

"Hand me that little green book. I may have to be up all night, and I
want something to read that will keep me awake," and the colonel
slipped into his coat pocket the green volume. He was taking his
fishing by a sort of "correspondence school method" it will be observed.

The detective busied himself about his apartment getting ready to go
out, and from a suitcase which was closed with a complicated lock he
took a number of articles which he stowed away in various pockets of
his garments.

"Is yo' gwine be out all night, Colonel?" asked Shag.

"I can't say. I'm going to do a bit of shadow work and it may take me

The colored servant unhooked the receiver and listened a moment. Then,
carefully covering the mouthpiece with his hand, he announced:

"It's Mr. Young, Colonel!"

"Is it! Good! Hold him! I'll talk with him!"

Quickly crossing the room the detective spoke rapidly into the
instrument.

"Hello, Jack! This is the colonel. Yes--what is it? He is? That's
unusual--for him. Guess he's going down and out by the wrong route!
Yes, I'll come right away! You follow King and I'll take the trail
after Larch. So he's boasting that-- Well, all sorts of things may
happen now. Yes, I'm on my way now. You follow King!"

The detective remained motionless for a few seconds after he had
slipped the receiver into its hook. Then he said to Shag:

"Do you know where I ought to be now?"

The colored man paused a moment befor
