"I am very sorry, your grace, that there should have been any misapprehension."

"You idiot!" were the words that arose spontaneously to the duke's lips; but they were not uttered. The "princely Hereward" habitually governed himself.

"Why did you not tell me in your telegram who was found?" he demanded.

"I certainly thought that your grace would have understood. In the telegram dispatched at nine o'clock yesterday morning, I told your grace that I had a clew to the woman who had called at Elmthorpe House on Tuesday. In the telegram sent at three in the afternoon, I said—'She is found.' I certainly thought your grace would understand that the woman to whom I had gained the clew was found. I grieve to know how much mistaken I was," sighed Mr. Setter.

"Ah! that accounts for everything. I never received that first telegram."

"Your grace never received it?"

"Certainly not."

"Then my messenger was false to his trust. I was so indiscreet as to send it to the office by a ticket porter, believing the fellow would do his duty faithfully, after having been paid in advance. The more fool I. I am certainly old enough to have known better!" said the detective, with a mortified air.

"Well Mr. Setter, it is useless to regret that mistake now. Be so good as to call a cab. We will go at once to Westminster Road and see this Mrs. Brown. What information has she given you?"

"None whatever, except this, which we knew before—that she visited the bride on the afternoon of the wedding day. She declines to tell me the nature of her business with the duchess; but says that she will explain it to you; she further denies all knowledge of the present abode of the duchess."
