Ferris and Macklin jumped to their feet and both rushed out in the hall.
"What's the row, Mary?" cried the latter.
"Sure an' that's phot Oi want to know," replied the woman. "Oi found this fellow pakin' in the kay-hole of your dure, so Oi did."
"It's Hal Carson!" exclaimed Ferris. "So this is the way you followed me, eh?" he continued.
"Who is Hal Carson?" asked Macklin, grasping the youth by the arm.
"Old Sumner's new clerk and office boy," replied Ferris. "Don't let him get away."
Macklin gave a whistle.
"Dat's kinder serious, if he follered yer here. Wot have yer got ter say fer yerself?" he demanded, turning to Hal.
"Let go of my arm," returned Hal. "Are you the only one who lives in this building?"
"No."
