"Shall I send off a description of the man to the police in the neighbourhood, sir?" Brennan asked.
"Did you not do so at once?" Durham asked, swinging round sharply.
"I was preparing it when you arrived, sir."
"We will look at the safes," Durham said.
Harding had pushed-to the doors of the big safe As he pulled them open Durham pointed.
"What keys are those?" he asked.
In the lock of the reserve recess the keys Eustace gave Harding in the morning were still hanging. Harding took them out.
"They are the manager's keys," he said. "In the excitement of the discovery that all the gold had gone, I must have forgotten to return them. I had no idea they were here when you asked me what Eustace had done with the keys. I entirely forgot them."
"But he did not, Mr. Harding. Do you know where he kept his private papers?"
"That was his private office," Harding replied, pointing to the little ante-room.
