"I'm sorry I hit you, Manfred," he said. "But when I caught sight of that infernal plant I felt sure that you had sold me. But even you couldn't have carried the thing off quite so coolly as that. And yet—and yet there can't be two Cardinal Moths in existence."

"There are not," Manfred said impatiently. "That is the same one I hoped to have had in my possession to-night. Didn't Frobisher say it had recently fallen into his hands?"

"I recollect that now. Manfred, I'm done. And yet I regarded it as a certainty."

"You were a great fool to strike me just now," said Manfred, thoughtfully, and without resentment. "Why? Because the blow told Frobisher that he had gained possession of the very thing you were after. It was as good as telling him that you thought I had betrayed you. To-night when the Shan dines——"

Lefroy grasped Manfred's arm with crushing force.

"He isn't going to dine with Frobisher to-night," he whispered. "We shall dine there, but his Majesty will be unfortunately detained owing to sudden indisposition. In other words, he will be too drunk to leave his hotel. Let's go into your lodgings and have a brandy and soda. I've got a plan ready. There is just a chance yet that I may succeed."

Manfred let himself into a house just off Brook Street. In a modest room upstairs, a box of cigars, some spirits, together with a silver jug of water, and a box of sparklets were put out. On the round table lay an early edition of an evening paper that Manfred opened somewhat eagerly for him. He glanced over a late advertisement in the personal column and shook his head.

"It is as I thought," he said. "See here. 'The butterflies have gone away and cannot be found. My poor friend has broken his neck and I have gone on a journey'—That is addressed to me, Lefroy. It is a message from my man that somebody has stolen the Cardinal Moth, and that my man's confederate has met with a fatal accident. Also it seems likely that there will be a fuss over the business, so that my correspondent has gone somewhere out of the way. We will look for some account of the tragedy presently; it is sure to be in this paper. Now tell me what you propose to do."

Lefroy poured a brandy and soda down his throat without a single movement of his larynx.

"I'm in a devil of a mess," he said frankly. "I made certain of getting the Cardinal Moth."
