on's
signature which I have appended to a letter now in my pocket. But there
are certain formations in the letters that lead me to suppose this
signature on the will is a rank forgery. I'm going to prove that idea
by giving the will and some of Mr. Dalton's signatures to a handwriting
expert. He will magnify them and throw the image of the enlarged
signatures on a screen by means of a magic-lantern. Any one can then
tell at a glance if this signature is a forgery or not."

"You'll do nothing of the kind!" yelled Mason, furiously.

"Won't I? You'll see, sir. I shall."

"That will shall be filed for probate with the surrogate."

"So it shall," grimly answered Old King Brady. "So it shall. And this
lawyer will contest it on behalf of Miss Dalton, and baffle your design
to rob her. And if it is proven that the will is a forgery, you can
rest assured that I'll arrest you for the crooked work the moment I get
my hands on you!"

Mason gave a hollow, mocking laugh.

"Fool!" he hissed. "I don't fear you."

"But you shall----"

"Bah! Shut up! You make me sick!"

And snapping his fingers at the old detective, Mason rushed from the
room, put on his hat and left the house.

When he was gone, Harry hastened after him.

Left alone with the girl and the lawyer, Old King Brady held a
conference with them and settled upon a plan of legal action.

In the meantime Mason had gone downtown, with Young King Brady
carefully shadowing him at a safe distance.

He entered Mr. Dalton's office and remained there until long after all
the clerks had gone home.

Harry remained outside the building on the watch for him, and at about
seven o'clock saw him emerge.

He dropped a letter in a lamp-post letter-box and rapidly strode across
town and entered a liquor saloon.

Young King Brady divested himself of his disguise in a hallway.

While waiting for his man to emerge from the saloon, the boy made a
bundle of the disguise and wrapped it in a newspaper.

Half an hour passed by.

Getting uneasy over the prolonged absence of the man, Harry strode into
the saloon, glanced around and failed to see Mason.

"He must have given me the slip!" thought the boy, ruefully.

"Looking for any one, sir?" queried a bartender who was watching him.

"Yes. What became of a fellow of this description who came in here half
an hour ago?" said Harry, and he minutely described Mason.

"Why, he went out the side door after getting a drink of whisky,"
