"Or rather, I fancy, of that goose. It was one bird, I imagine in which you were interested–white, with a black bar across the tail."

Ryder quivered with emotion. "Oh, sir," he cried, "can you tell me where it went to?"

"It came here."

"Here?"

"Yes, and a most remarkable bird it proved. I don't wonder that you should take an interest in it. It laid an egg after it was dead–the bonniest, brightest little blue egg that ever was seen. I have it here in my museum."

It seems to me, Ryder, that there is the making of a very pretty villain in you. You knew that this man Horner, the plumber, had been concerned in some such matter before, and that suspicion would rest the more readily upon him. What did you do, then? You made some small job in my lady's room–you and your confederate Cusack–and you managed that he should be the man sent for.
