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.
