As soon as he had heard Harding's account of what had happened, he produced the handkerchief bearing Eustace's name.

"Can you identify that?" he asked. "It is marked, but I want to know if you can recognise it apart from the name it bears?"

"It is like the handkerchiefs I use," Harding answered, as he pulled one out of his pocket. "Eustace and I ordered some to be sent up, and we divided them, taking half each."

"Did you mark them?"

"Mrs. Eustace did that for us. Is the name on this?"

He turned it round until he saw the name.

"Yes, that is one of Eustace's," he said.

"What time do you think it was when you saw that man's face at the window?" Durham inquired.

"Between half-past nine and ten--nearer ten probably."

"Was the face familiar?"

"It was, but I cannot recall where I have seen it before. It struck me as being a familiar face disguised. It was not Eustace's."

"You feel sure of that?"

"I'm quite sure. I wish you had been here to have seen it."

"I did see it."

"But you were at Waroona Downs."

"So I was. It was there I saw it. That man and his companion stuck the house up. I was asleep on the verandah and they must have crept on me, for when I awakened I was bound hand and foot. The man you describe was standing in front of me. When I attempted to shout to warn Mrs. Burke, a handkerchief was pressed over my mouth and tied by someone who kept behind me. That is the handkerchief which was used. Who would you say tied it?"

"I should suspect Eustace, of course; or do you think the man with the beard was Eustace?"

Durham shook his head.

"No," he said. "The description I have of Eustace does not agree at all with the build and general appearance of that man. If Eustace were there at the time he must have kept behind me. Is Mrs. Burke a woman who talks much?"

"Talks? She does nothing else. She tells everyone everything."

"Then it is no use my trying to keep this episode of the handkerchief quiet?"

"Not if she knows anything about it. She will tell everyone about it directly she comes to the township."

"Oh, she knows about it. She is a plucky woman. She drove them off, firing at them; then she discovered me on the verandah and nearly shot me into the bargain. When I was set free this handkerchief was on the verandah and she saw it as soon as I picked it up."

"Then everyone in the township will hear about it," Harding said. "She is to come in this afternoon to meet Mr. Wallace."

"When is he due?"

"About noon he ought to be here."

"Then I'll ride out and meet him," Durham said shortly. "Is there anyone in particular who was with the crowd last night to whom I can go for further information?"

"Mr. Gale was one."

"I'll see him," Durham said, and left the bank, finding Gale in the street discussing the latest raid with half a dozen other men of the town. He left them at once and came over to the sub-inspector.

"Look here, it's no use wasting more time," he exclaimed warmly. "We all say there is only one thing to be done if those scoundrels are to be caught. We must scour the ranges. I'll volunteer and so will everyone else in the place. The only hope is to ride them down."

"Quite useless," Durham replied curtly.

"It's the only course to adopt," Gale retorted. "We're all bushmen here and know what's the proper thing to do. You can't apply town methods to bush-rangers, you know. You may be the smartest man in the force at catching city burglars and spielers, but you are out of your element in the bush. There's only one thing to be done--track them down."

"How many are there?"

"Well, two for certain--probably more."

"Probably more--exactly. And most probably one or other of the remainder is in the town acting as a spy for the others. If that is so, what will happen when you set out in force? Everyone would volunteer, as you say, and one of the number would give warning of what was being done. What chance would there be then of making a capture? You tried last night.

What was the result?"

"We found their tracks."

"Then why didn't you follow them?"

"Because with the crowd riding all over the ground we lost them, and----"

"Just so," Durham interrupted. "It is what would happen again if your suggestion were carried out. This is a one man's job, Mr. Gale. Directly I want a.s.sistance I will come to you, but in the meantime I must ask you to keep your fellow-townsmen from interfering."

He went on to the police-station, leaving Gale to convey his refusal of a.s.sistance to the men who were keen on taking the matter into their own hands. The refusal was received with open resentment and the group moved towards the station to argue the matter out with the sub-inspector, but before they reached it Durham rode out of the yard and set his horse to a gallop along the road leading to the railway.

"It's all right, boys, he's got a clue," one of the men exclaimed scornfully. "He's going to catch them at the junction!"

"Give him a cheer for luck," another cried, and the ironical shout reached Durham as he galloped. But he paid no heed to it, riding on steadily till he was away from the town and some miles along the road when he saw, coming towards him, a pair-horse buggy accompanied by a couple of mounted troopers. As they came nearer he recognised Wallace in the buggy. The troopers drew to the side of the track as he reined in beside the vehicle.

"Come back along the road a bit," he exclaimed, as he got off his horse and gave the bridle to one of the troopers.

"Why are these troopers with you?" he asked when he and Wallace had walked out of hearing.

"I have close on thirty thousand pounds in the buggy. I have had to bring with me not only sufficient funds to enable the bank to carry on its ordinary business, but a further twenty-five thousand in gold to carry through the purchase of Waroona Downs from Mr. Dudgeon."

"Why is it necessary for all this gold to be used? I did not care to ask Mr. Harding, but if it is not a bank secret----"

"Oh, it is no secret," Wallace exclaimed. "Mr. Dudgeon had a quarrel with the bank some time since, and, in addition to giving himself a great deal of unnecessary trouble, he delights in making everything we have to do with him as unpleasant and difficult as possible. Any payments we have to make to him have to be made in gold. He is legally ent.i.tled to demand it, and he avails himself of his right to the utmost.

That is why I have had to push through with the amount so as to be able to complete Mrs. Burke's purchase to-day. As we were not anxious to lose another twenty-five thousand, we obtained an escort from head-quarters, but I fancy the men have to return to-night."

"Eustace would know this second amount would have to be sent up?"

"Of course he would."
