Murk had a little money Prale had given him, enough to pay the taxi chauffeur. Prale motioned for him to approach.
"Here's a roll of bills," he said. "Keep up the game, Murk. Don't get too far away."
"I'll be right at your heels, boss."
"And keep your eyes open."
"Yes, sir."
"That woman was Kate Gilbert."
"Then I'll know her whenever I see her again, sir."
Prale hurried on down the path. Murk kept pace with him, a short distance behind.
Kate Gilbert had been walking swiftly. She had reached the street, and, as Prale watched, she crossed it. Prale followed.
The girl did not look behind. She came to the middle of the block and ran up the steps of an apartment house. Prale passed the entrance, glanced at the number, and continued down the street. At the corner he allowed Murk to catch up with him.
