"Dr Mortimer's is farther down the street," said the sergeant, "so you've made a big mistake in playin' the fool here, and giving me cheek. You've got to come to the station, every man jack of you, and the quieter you come the better it will be for you in the morning."

Now the Welshman--acknowledged leader of the band--spoke up.

"Look here, bobby," he said, "we'll go to the station, but we're not going to be marched off like pickpockets. If you keep to the left-hand pavement, we'll keep to the right, and I'll give you my word of honour for the lot that we won't cut."

The Welshman had a good pair of eyes, and the stout sergeant was an old hand at summing up character at short notice. He conferred briefly with his men.

"Very well," he said, at length, "I'll agree to that. First give me your name and address, though."

The Welshman handed him his card. The sergeant made a sign, and the police withdrew. Then the Welshman formed his men up in single file, gave the word to "March!" and led them in good order out of the surgery and down Mount Street, keeping them to the edge of the right-hand pavement. The sergeant, true to his compact, kept his men to the left-hand pavement, the bearded man walking sulkily by his side.

It is now necessary to return to Jim and his movements.

This had been a very hard day with the Long 'Un, who had been out and about constantly, for there was much sickness in the district. Some of Jim's frequent emergings were witnessed by young Isaac Harris, who, as often as his duties in the shop permitted it, took up a position on his step and watched the surgery door.

For, ever since Jim, before Rebecca Nathan's very eyes, had expelled Isaac from his surgery in the manner recently described, Isaac had been thirsting for revenge. And to-day an excellent idea had entered his head. The chief of the Hooligans still looked in at the Harris emporium for odd meals, and Isaac fancied that this nice gentleman would serve as a convenient instrument in the matter of harming Dr Mortimer. Isaac knew that the Hooligans bore Jim plenty of ill-will, and would be only too pleased to get an opportunity to wreak their spite against him. And it struck Isaac that their most favourable opportunity would occur at night-time, when Jim was attending a patient in one of the narrow courts in which the locality abounded.

The Hooligan leader had been in that afternoon, and Isaac had lost no time in sounding him about Jim. The Hooligan's sentiments and hopes were expressed in brief but blasphemous terms.
