"Read it," he said. "There's no answer. I'll join you presently."

Harding left the room, glancing at the message as he crossed the pa.s.sage. It required no answer, as Eustace had said. It was very brief.

"Inspector Wallace will take charge."

Harding whistled. Wallace was the senior inspector of the service, and his special faculty was the unravelling of tangled accounts and the detection of defaulting managers and cashiers. Leaving the ordinary inspection of branches to his juniors, Wallace only journeyed from the head office to take charge when grave suspicions were entertained as to the integrity of a branch staff. The telegram was tantamount to an intimation that the authorities of the bank did not regard the robbery as the work of an outsider.

As he re-entered the office, Brennan was standing at the entrance with Johnson.

"No answer," Harding said quietly, and Johnson nodded and went off.

Brennan turned and crossed to the counter.

"Is Mr. Eustace about?" he asked.

"He is talking to Mrs. Burke in the dining-room. She's rather excited, and he took her in there because she would shout so. He'll be back in a few minutes, unless you want to tell him something particularly at once," Harding answered.

Brennan glanced at a telegram he held in his hand.

"It will do when he comes out," he answered slowly. "Have you had any word?" he added, as he leant over the counter.

"The head office wires that Inspector Wallace--our bank inspector, that is, not one of your police inspectors--is coming up."

"Is that all?"

Harding gave a short laugh.

"All? It's quite enough, Brennan. Between you and me it means that Eustace and I are suspected--one of us or both."

"Yes, that's right," Brennan said quietly. "One or both."

As he spoke he held out a message for Harding to read.

"Keep manager under close surveillance till I arrive.

"DURHAM."

"You know who Durham is?" Brennan asked.

"Never heard of him," Harding answered.

"He's the finest man who ever put on a uniform," Brennan exclaimed. "He is the sub-inspector in charge of this district--he's only been appointed a couple of months. I reckon it's only a temporary thing for him, just until there's room to make him an inspector. It's a good thing for your bank he is coming up. If anyone on earth can unravel a mystery, my sub-inspector is the man. He won't be long before he has the matter cleared up."

"If he can get to the bottom of this business, I'll agree with you,"

Harding replied. "But I don't think very much of his first idea; I don't think he is right if he suspects Eustace. When do you expect him?"

"I should say he will be here some time during the day. He wired from Wyalla, and I expect he'll ride across country--it will be quicker than waiting for a train at the junction. Ah, there's Mr. Gale back," he exclaimed, as a buggy drove past the bank. "If you'll let me know when Mr. Eustace is free, I'll just step out and hear what he has discovered about the yarn the men told us."

"All right. I'll call you as soon as Eustace comes in," Harding said, and Brennan left the office.

Soon after he had gone Harding heard the dining-room door open and Mrs.

Burke's voice ring through the house.

"I don't believe a word of it. It's false; it's untrue. It's all a blind. I'll see whether there is not justice in the land for an unfortunate widow robbed of her all."

Then the door was slammed and the front door opened and slammed also.

Harding sat waiting for Eustace to come back to the office. He heard Mrs. Burke's voice sounding shrill outside, but not clear enough for him to distinguish what she was saying. Then the buggy started and drove rapidly away.

A gentle tap came at the door leading to the house, and Mrs. Eustace opened it and looked in.

"Has that dreadful woman gone?" she asked in an agitated voice. "Is Charlie here?"

Harding rose and went over to her.

"No. He has not come back yet. He is in the dining-room. Shall I tell him you want him?"

"Oh, no, perhaps it will be better to leave him alone till he comes out.

Did you hear what she said? She has been making such a scene in there.

Poor Charlie, as if he had not enough to worry him as it is, without her saying such terrible things."

Brennan, with Gale and Johnson, appeared at the entrance, and Mrs.

Eustace went back into the house, closing the door after her.

"Mrs. Burke has gone," Brennan said, as he came over to the counter. "Is Mr. Eustace in the office?"

"He has not come out of the dining-room yet. Shall I tell him?" Harding replied.

"I'll go through," Brennan said.

Harding opened the door and stood holding it, with Gale and Johnson behind him, as Brennan went to the dining-room door and knocked.

Receiving no answer, he opened the door.

"There is no one in there," he called out.

With one accord the three moved forward. Brennan was half-way across the room when they reached the door. He went to the window and looked at the fastening.

"He did not get out this way," he cried. "He must be in the house somewhere."

Mrs. Eustace appeared on the stairs, and came down.

"Where is your husband, Mrs. Eustace?" Brennan exclaimed directly he saw her.

"He was in there--isn't he in there now?" she said, as she pa.s.sed into the room.

"He is not here, Mrs. Eustace, though Mrs. Burke left him here when she came out a few minutes ago. Where is he?"

With widely open eyes Mrs. Eustace stared from one to the other.

"Oh, what is it?" she cried. "What is it? Tell me--is it----"
