"He's lying in prison, waiting to take his trial for murdering young Mr. Carson."
So, indeed, it was. At the inquest the policeman who had witnessed the quarrel between the rivals testified to the threats uttered by Jem; and the gun used by the murderer, and thrown away by him in his haste to escape, had been proved to be Jem's property.
Jem an assassin, and because of her! In the agony of that night Mary saw the gallows standing black against the burning light which dazzled her shut eyes, press on them as she would. She thought she was going mad; then Heaven blessed her unawares, and she sank to sleep.
She was awakened by the coming of a visitor. It was her long-lost, unrecognised aunt Esther, who had come to her niece bringing her a little piece of paper compressed into a round shape. It was the paper that had served as wadding for the murderer's gun. Esther had picked it up while wandering in curiosity about the scene of the murder. There was writing on the paper, and she had brought it to Mary, fearing that if it fell into the hands of the police it would provide more evidence against Jem.
The paper told Mary everything. It had belonged to John Barton. Jem was innocent, and her own father was the murderer! Jem must be saved, and she must do it; for was she not the sole repository of the terrible secret? And how could she prove Jem's innocence without admitting her father's guilt?
When she could think calmly, she realised that she must discover where Jem had been on the Thursday night when the murder had been committed. Tremblingly she went to Mrs. Wilson, and learnt what she wanted to know. Jem had walked towards Liverpool with his cousin Will, a sailor who had spent all his money in Manchester, and could not afford railway-fare. Will's ship was to sail on Tuesday, and on Tuesday Jem was to be tried at the Liverpool assizes.
Job Legh engaged a lawyer to defend Jem, and Mary prepared to go to Liverpool to find the one man whose evidence could save her lover. Ere she left, a policeman brought her a bit of parchment. Her heart misgave her as she took it; she guessed its purport. It was a summons to bear witness against Jem Wilson at the assizes.
IV.---"Not Guilty"
Arrived at Liverpool on Monday, after the bewilderment of a railway journey--the first she had ever made--Mary found her way to the little court, not far from the docks, were Jem's sailor cousin lodged.
"Is Will Wilson here?" she asked the landlady.
