Mrs. Challoner shivered at the prosecutor's earnestness; but Challoner, hesitating for a moment only, advanced and said:—

"We'll take it. I'm not a bit afraid now, Murgatroyd—for I know." And then holding out his hand, he continued kindly: "Billy, if you hadn't taken it—where would I have been to-day?"

"Free—free as you are now," said the other man in a low, strained tone.

"Yes," assented Challoner, "out of prison, but——"

Mrs. Challoner quickly rose and put an end to the conversation going on between the men.

"Come, Laurie," she said abruptly; and holding out her hand, "good-bye, Mr. Murgatroyd! I'm afraid we have taken up altogether too much of your time."

Murgatroyd shook hands with the Challoners; but on Shirley making her adieus, he said:—

"May I have a moment with you, Miss Bloodgood? Won't you wait, please?"

Mrs. Challoner answered for the girl:—

"Shirley, don't be in any hurry. Laurie and I will wait for you in the ante-room—" And as they passed out Challoner called: "Wait until you see that concrete hospital, Murgatroyd!"
