The half hour gave Jack time to get to Evers' and change his make-up. It was not yet eight o'clock.

Evers evinced a strong interest in Tommy when he arrived. "Comical little fellow, isn't he?" he said. "That wiry, blonde hair betokens an enterprising character. These boys of the street learn to think for themselves early."

Tommy and Jack did not discuss their business of course, until they had left the shop. Outside Jack said:

"Do you mean to say you have spotted the house where the old man lives?"

"Not where he lives, but where he changes his clothes."

"Good man! Where is it?"

"Forty-Eighth street, near Seventh avenue."

"We'll go there," said Jack, and looked up and down for a taxi-cab. "You can tell me the whole story on the way. We'll stop at the Madagascar for a gun and a pair of handcuffs in case we meet our friend."

When they were seated in the cab Tommy began his story. "I was thinking over everything you told me, and it seemed to me I wouldn't have a very good show to trail the old man by myself. Maybe he knew my face you see, and anyway the uniform was a give away. So I got my cousin to help me. He ain't working now. He's bigger'n me. We're going partners in the detective business when we get the coin to open up an office."

"I described him the man I was after, and placed him acrost the street from the office, with instructions to follow me if I come up, and pick up the trail if I had to drop it."
