She professed herself as understanding perfectly and went off in quite a flutter of satisfaction to accomplish her task. But though he did not know it at the time, it seems that her heart failed her when she got into the hall, and struck with fear lest she should forget the numbers before she got to the foot of the stairs, she came back, and carefully wrote them down on a piece of paper, armed with which she started for the second time to fulfil her task. The watchman was in the bank when she entered, and to his expressions of surprise, she answered that her husband was ill and that she was going to open the vaults. He offered to help her, but she stared at him with astonishment, and waiting till he had walked to the other end of the bank, proceeded to the vault door, and after carefully consulting the paper in her hand, was about to turn the knob as directed, when Hopgood himself came into the room. He was too anxious, he said, to keep in bed, and though he trembled at every step, came forward and accomplished the task himself. He did not see the paper in his wife’s hand, nor notice her when she tore it up and threw the pieces in the wastebasket nearby, but the watchman may have observed her, and as it afterwards proved, did; and thus became acquainted with the combination that unlocked the outer vault doors.”
“Humph!” broke in Mr. Sylvester, “if this is true, why didn’t Hopgood inform me of the matter when I questioned him so closely?”
“Because he had forgotten the circumstance. He was in a fever at the time, and having eventually unlocked the vault himself, lost sight of the fact that he had previously sent his wife to do it. He went back to his bed after the clerks came in, and did not get up again till night. He may have thought the whole occurrence part of the delirium which more than once assailed him that day.”
“I remember his being sick,” said Bertram; “it was two or three days before the robbery.”
