m going to make you rock with
joy and merriment!"

The figure had moved to the table, and all the time it spoke its nimble
fingers were turning over the piles of documents which the colonel had
disgorged from the dispatch box.

"I'm going to tell you a comical tale about a gang of blackmailers."

"You're a liar," said the colonel hoarsely.

"About a gang of blackmailers," said the Jack with shrill laughter,
"fellows who didn't work like common blackmailers, nor demand money. Oh,
no! not naughty blackmailers! They got the fools and the vicious in
their power and made them sell things for hundreds of pounds that were

one white face to the other.

"There's a hundred thousand pounds for any one of you who gets that
fellow," he said, breathing hard, "whether it is man or woman."

CHAPTER III

THE DECOY

Colonel Boundary, sitting at his desk the morning after, pushed a bell.
It was answered by the thick-set Olaf. He was dressed, as usual, in
black from head to foot and the colonel eyed him thoughtfully.

"Hanson," he said, "has Miss Marsh come?"

"Yes, she has come," said the other resentfully.

"Tell her I want her," said the colonel and then as the man was leaving
the room: "Where did you get to last night when I wanted you?"

"I was out," said the man shortly. "I get some time for myself, I
suppose?"

The colonel nodded slowly.

"Sure you do, H
