Five minutes more went by--to poor Ralph they seemed an age. Then the boy fancied he heard a light footstep without.

"Hullo! where are yer?" came in a clear but subdued voice, which Ralph was sure he had heard before.

The cry was repeated several times. In the meanwhile Ralph changed his position and began to kick upon the door.

"In the kitchen closet, dat's where he is!" exclaimed the voice, and the patter of bare feet came toward Ralph's prison.

A second later the bolt on the door was shot back. A flood of light came into the place and Ralph beheld the face and form of the bootblack he had become acquainted with at the entrance to the post office.

"I t'ought so!" exclaimed the bootblack. "Say, he's a corker ter treat yer dis way, ain't he?"

Then he saw how Ralph was gagged and bound, and he gave a low whistle of surprise.

"Gee! What's dis, highway robbery?" he cried.

In a trice he had out his pocketknife and with it he cut Ralph's bonds.

Ralph himself removed the gag.

"Thank you, Mickety!" he e.j.a.c.u.l.a.t.ed, as he sprang to his feet. "You are the friend in need!"

"I seen him leadin' yer up here, an' I t'ought it was mighty queer," said the bootblack. "Wot's de game?"

"I am as much in the dark as you, Mickety. That man has tried twice before to take my life."

"Gee! yer don't say!"

"It is true."

"Maybe he wants ter git a fortune away from yer, like der villain in der play."

"There is no fortune to get away--at least none that I ever heard of. But where has he gone?"

"He went down der street. I watched him around der corner before I came up, so as ter make sure I wouldn't be collared."

"We had best get out of here before he comes back," went on Ralph, after a moment's thought. "I do not wish to meet him again," and he shuddered.

"All right, come on."

"What brought you here?"

"I live across der street, an' I just come home fer me grub. I kin take yer ter our rooms if yer want ter come."

"I will tell you what I would like to do, Mickety. I would like to stay here until he comes back, and then follow him."

"Gee! dat's der ticket. Come on right over."

The bootblack led the way across the dirty and crowded street, and into an alleyway.

"Me home is back dere," he said, pointing to a rear tenement. "I don't suppose yer want ter come in, if yer goin' ter watch fer dat man."

"No, I will stay here," returned Ralph.

"I'll git a bit of grub an' den come out ag'in," said Mickety.

He ran off, leaving Ralph alone. The crowd of street children looked at the country boy, but they had seen him talking to Mickety, with whom they were well acquainted, and they did not offer to ask Ralph any questions or tease him, as they might an utter stranger.

In less than a quarter of an hour the bootblack was back, munching the last of a big doughnut.

"Ain't come yet?"

"Not yet, Mickety."

"Kin I stay an' help yer watch fer him?"

"If you wish, certainly."

"He may try to do yer ag'in, an' I kin call a cop."

"That is so. Yes, stay with me, and I will pay you for your trouble."

"Huh! don't want no pay, Mr. ---- Yer didn't tell me yer name."

"Ralph Nelson."

"I ain't askin' fer no pay, Mr. Nelson. Dis sort of a job is nuthin' but fun."

"You may be of valuable a.s.sistance to me," went on Ralph. "I may have that man arrested. You can prove that he bound and gagged me, and locked me up in the closet."

"Dat's so."

"I want to find out what his object is. He may----"

Ralph broke off short and pointed across the street.

"Dat's him, true enough!" whispered Mickety, as Martin entered the tenement opposite. "Wot yer goin' ter do now?"

"Wait till he comes out."

This did not consume much time. In less than three minutes after he had entered the building, Martin came running out. He looked greatly disturbed and hurried down the street as fast as his long legs would carry him.

"Dere he goes!" exclaimed Mickety, in ill-suppressed excitement.

"Come on," returned Ralph. "He must not get out of our sight."

He started off, with the bootblack at his side. He looked at Mickety and saw that the little fellow's head was about the size of his own, and that he wore a large-brimmed soft hat.

"Let us trade hats for a while, Mickety. I can pull that down over my face."

The exchange was quickly effected. With the soft hat bent down Ralph knew he would stand a much greater chance of escaping detection at the hands of Martin than before.
