“It’s so nice having Mr. Lanner here,” confided Mrs. Olston to Clovis the next afternoon; “he’s always been engaged when I’ve asked him before. Such a nice man; he really ought to be married to some nice girl. Between you and me, I have an idea that he came down here for a certain reason.”

“I’ve had much the same idea,” said Clovis, lowering his voice; “in fact, I’m almost certain of it.”

“You mean he’s attracted by—” began Mrs. Olston eagerly.

“I mean he’s here for what he can get,” said Clovis.

“For what he can get?” said the hostess with a touch of indignation in her voice; “what do you mean? He’s a very rich man. What should he want to get here?”

“He has one ruling passion,” said Clovis, “and there’s something he can get here that is not to be had for love nor for money anywhere else in the country, as far as I know.”

“But what? Whatever do you mean? What is his ruling passion?”

“Egg-collecting,” said Clovis. “He has agents all over the world getting rare eggs for him, and his collection is one of the finest in Europe; but his great ambition is to collect his treasures personally. He stops at no expense nor trouble to achieve that end.”

“Good heavens! The buzzards, the rough-legged buzzards!” exclaimed Mrs. Olston; “you don’t think he’s going to raid their nest?”

“What do you think yourself?” asked Clovis; “the only pair of rough-legged buzzards known to breed in this country are nesting in your woods. Very few people know about them, but as a member of the league for protecting rare birds that information would be at his disposal. I came down in the train with him, and I noticed that a bulky volume of Dresser’s ‘Birds of Europe’ was one of the requisites that he had packed in his travelling-kit. It was the volume dealing with short-winged hawks and buzzards.”
