“If the Everetts are leaving, why should Miss Prall go to the trouble of eliminating the Bun man?”

“Point well taken, Zizi; but, you see, as long as the Bun man was around he nagged at nephew to go into Buns and give up his more congenial occupation.”

“Pretty slim reason for a real live murder, I think.”

“So do I. But it’s the best we can get in that direction. Now, coming to the Everett suspects, the widow may have more reason for wishing Sir Herbert dead than we yet know of.”

“All we know of is so he can’t push along the romance of the youngsters.”

“Exactly. And here’s the conclusion of the whole matter. I conclude that those two women are the ones to be looked up, not, of course, acting together, but one or the other of them. If we can get anything on either, let’s do so.”

“And the business men?”

“I want to look those up, too. There’s one Crippen, who considered buying out Sir Herbert’s business. Also, he was an old beau of the two enemy women. There may be a complication worth studying there.”

“What is this bun business? I mean, does he merely sell the good will,—of what?”

“Oh, no; he sells his recipe. It’s a secret process,—the making of Binney’s Buns,—and the recipe is the thing. No one has ever been able to imitate them successfully. All attempts are dismal failures. But with the formula any one can make them. It’s Sir Herbert’s great source of anxiety lest the recipe, or formula, whatever they call it, should be discovered.”
