Mr. Pardoe, the active police officer of York, was employed to ascertain to whom the shoemaker's pincers belonged, and they were owned by Mr. Lawn, at whose house Martin had lodged. Other circumstances formed a chain of evidence so complete and conclusive as to leave no doubt that Jonathan Martin was the incendiary, and hand-bills were issued on Thursday offering a reward for his apprehension. Pardoe had been despatched to Leeds in pursuit the previous day, with a warrant from Archdeacon Markham, which on his arrival was instantly backed by the Mayor of the borough. For the rest of the day and during the night Pardoe and the whole force of the police were employed in endeavouring to find a clue to the retreat of the incendiary. They were not successful; but on Thursday morning his wife was taken into custody while vending the "History of his Life." When discovered by the officers, she expressed her surprise at the charge against her husband; and after admitting that he left that town on Saturday morning, said that she understood, on his departure, he was going into the neighbourhood of Tadcaster; that she had not heard of him since; and that she had experienced great uneasiness at his long absence. She added that his place of concealment, or anything further connected with the affair, was totally unknown to her. She was kept in custody at Leeds, in her own house, in the charge of two constables, who obtained possession of all Martin's books and papers. On Thursday morning information was received which caused an express to be sent off to the neighbourhood of Pontefract, where an active and diligent search was commenced. A clue was obtained, which led to the belief that the incendiary had passed through Pontefract on the road to Wakefield. The Mayor of Pontefract ordered the police of that town to afford every assistance to the gentlemen in pursuit, and he was traced to Polston toll-gate. From the information there obtained it was supposed he had taken the direction to Heath; and the pursuit was immediately followed up in that direction, and continued through most of Friday. It was reported in the evening about seven o'clock that Martin had been captured about five miles from Bedale, and would be brought into York by the Carlisle Express coach. The coach was half-an-hour beyond its time, and the streets were filled with crowds of anxious spectators, who waited in the expectation that the incendiary would arrive by it. Many persons went out of Micklegate Bar, and ran alongside of the coach till it stopped in Coney Street. It was then found that the report was an erroneous one, for Martin was not there; nor was it true that he had been captured.
