“It’s at the very top,” Cassy told him, and finally her door was reached and they went in. “This is Rock,” said Cassy to her mother, “and he’s going to find Jerry.” She spoke with confidence.

Rock, seeing the sweet-faced woman who spoke with such a gentle voice, did not wonder that Cassy seemed such a little lady. She looked like her mother and had just such a way of speaking.

“I suppose Jerry hasn’t come yet,” said Rock.

“No,” Mrs. Law replied. “He has been gone a long time for him; he is usually home to supper. I hope nothing has happened; that he——” she looked at Cassy, “that he has not been run over or anything of that kind,” she added, hesitatingly.

“Oh, I don’t believe that,” said Rock in an assured tone. “You know they say ill news flies swiftly, so we’ll think he has gone off some distance and has been detained. Cassy and I will find him. We will inquire around, for some one has seen him go, no doubt.”

“I am very much obliged indeed,” Mrs. Law told him. “I shall feel quite satisfied to have Cassy go if you are with her.” Therefore Rock and Cassy took their departure.

Rock’s first move was to inquire of the big policeman at the corner if he had seen Jerry Law since four o’clock. The policeman looked up and down the street and then at Rock and Cassy.

“Jerry Law, is ut?” he asked. “A small-sized lad ut lives next dhoor to that little haythin Billy Miles? I’ve not seen um. Howld on; I did thin, airly in the afternoon. There was a crowd of bhoys out be Jimmy McGee’s lumber yard, and I belave Jerry was with the lot.”

“Thank you,” said Rock. “You see he hasn’t come home yet, and his sister is worried.”

“He’ll be afther shtayin’ out later whin he’s a bit owlder,” said the policeman with a grin. “He’s not far off, I’m thinkin’. He’ll be playin’ somewhere, you’ll find.”
