"Now, sir, I am ready to receive your message."

"It's a verbal one," returned the detective, in a voice soft and smooth, not at all in keeping with his disguise, "and from Mr. Lamotte. I am the officer chosen by him to investigate for you, Miss Wardour, and as much time has been lost, I only wait your sanction and acceptance to begin the work."

The soft voice and polished accent were in very marked contrast to his dress and facial appearance. His manner of boorish discomfort had been dropped when the door closed upon outside observation.

Mentally contrasting the ease and suavity of this new comer with the cat-like movements and brusqueness of his predecessor, Constance, who began to realize the ludicrousness of the situation, in fact seemed to have some special private reason for finding it exceedingly absurd, replied that Mr. Lamotte's chosen officer must of course be acceptable to her, and that she only awaited his commands, if she could be of any service to him.

"Then," said Detective Belknap, "I may as well look over the premises, unless," turning upon her a searching look, "there are particulars concerning the robbery which Mr. Lamotte was not in possession of."

Constance lowered her eyes, in seeming effort to remember if Mr. Lamotte knew absolutely all; she thought of the chloroform, but the bottle had not yet been returned to her. What should she do? Before telling this part of the story she must have the bottle. Suddenly her woman's wit came to her aid. Looking up with sweetest candor into the detective's face, she said,

"I am the only one who possesses any information that was not known to Mr. Lamotte. It is a mere trifle, but as it will take some time in the telling, I will, if you please, order breakfast. You can scarcely have breakfasted at this hour. I will show you the library now. Will you look over that and the other rooms, and kindly excuse me for a short time? Then join me at breakfast, and I will give you my version of the story."

She arose as if considering the matter decided beyond question, and moved toward the door, and with a bow and a murmur of assent, Mr. Jerry Belknap fell into his assumed shamble, and followed her to the library. Leaving him there, Constance went out to order breakfast served in half an hour, and to send Nelly with the key to her dressing room.

"Nelly must be taken into my confidence," mused she, as she went in search of that damsel. "I can trust Nelly in spite of her Irishries, and if Doctor Heath does not appear soon she must help me out in some way."

Nelly was not at her post, having been dispatched kitchenward by Mrs. Aliston, and Constance went up to her own rooms, thinking, as she went, how best to defer a further interview with Mr. Belknap.
