The affair between Bates and Dorcas was, of course, known to both guardians, though they tried to disbelieve it, and probably didn’t know to what lengths it had already gone. But Mrs Everett knew that Sir Herbert approved the match and doubtless feared that her modern and up-to-date daughter might take the reins in her own hands. Therefore her desire to have Sir Herbert removed was explainable. She felt sure that without his Uncle’s insistence on Richard’s entering the Bun business, the young man would return to his inventions and so forget Dorcas in his work. At least, that’s the nearest Gibbs could come to her motive, though he felt sure there was more to be learned regarding that. Mrs Everett was deep and very plausible of manner. She had, he knew, underlying motives and hidden capabilities that would lead her, with the assistance of the Amazonian Kate, anywhere.

On the other hand, Miss Prall wanted the old man out of the say, so that her nephew would lack his advice and assistance concerning the affair with Dorcas, and the aunt felt that, with Sir Herbert out of it, she could easily persuade Richard to return to the great work in which he was so deeply interested and forget the girl. Moreover, she knew that Mrs Everett, no more desiring the marriage of the young people than she did herself, was planning to move away, and then all would be well.

The motives were not altogether clear, but, Gibbs reasoned, there must be many points that were hidden and would remain so, with these clever women to guard them.

He tactfully tried to draw them out, but with even greater tact they evaded and eluded his questions and contradicted each other and occasionally,—and purposely,—themselves, until the detective began to think the determined masculine mind is no match for the equally determined Eternal Feminine.

Indeed, involuntarily and almost unconsciously, they joined forces against him, and presently found themselves aiding each other, which, when they realized it, made them more angry,—if possible,—than before.

At last Mrs Everett looked at her watch.

“I’ve an appointment that I’m anxious to keep,” she said, drawlingly; “as you don’t seem to be getting anywhere, Mr Detective, can you not let me go, and finish up this absorbing discussion with Miss Prall?”

“You’re quite mistaken in assuming that I’m not getting anywhere, Mrs Everett,” returned the nettled detective, “but you may go if you wish. In fact, I allow it, because I have learned about all there is to learn,—not so insignificant an amount as you imply.”

Mrs Everett looked at him sharply and was momentarily disconcerted enough to gasp out:

“Oh, have you a clue?”
