"Charmed to oblige you, Miss Carew," said he in a gallant fashion; "but--you will pardon me--may I ask why you wish for this address?"

"Certainly," replied Dora, prepared for the question; "I have picked up a pearl brooch on the road"--she was afraid to state the actual finding-place--"which I have reason to believe belongs to Lady Burville. I wish to return it to her in person."

"May I see the brooch, Miss Carew?"

"Certainly."

She handed it to him in silence. Sir Harry examined it, noted the initials, and returned it with a polite bow and the required information.

"The address of Lady Burville," said he amiably, "is No. 22, Jersey Place, Mayfair. I am sure she will be greatly obliged to you for returning her brooch, which I recognise as one she usually wore. No doubt she dropped it on the road when out on her bicycle. But if it would save you trouble, Miss Carew, I should be happy to forward it myself."

"There is no necessity, thank you," replied Dora, rising to take her leave. "I am going up to town to-morrow, in any event, so I can easily return it myself. Good evening, Sir Harry. I thank you for your good nature in seeing me at this hour, and your kindness in giving me the address."

"Pray do not mention it, my dear Miss Carew. I am delighted to be of service to you."

During this conversation Sir Harry had discreetly refrained from remarking on the tragic end of Julian Edermont. He knew that Miss Carew was the ward of the dead man; but, afraid of a scene, and detesting trouble, he judged it wiser to ignore the fact. In the same way he gave the address of Lady Burville at once, as he was anxious to rid himself of his visitor. Sir Harry Hernwood, in a word, was a fool; and for that reason Dora was successful in her mission. A wiser man would have withheld the address of his late guest until better assured of the errand of the inquirer.

Dora thought of all these things as she rode homewards, and congratulated herself that Sir Harry had proved so foolish and weak. She had the address of Lady Burville, and could obtain the interview she sought. Now it remained to force the woman into confession of the crime by means of the pearl brooch. It would be difficult for Lady Burville to explain its presence in the study without inculpating herself in the murder.
