"Let me up, Hammer," I implored.

"My dear fellow, you're semi-delirious."

"I must get up," I muttered.

He laughed slowly.

"Not for another week or two, Harden. How is the black cat?"

"That cat is a wizard."

I lay watching him between half-closed eyelids.

"He gave me the idea."

"He gave you a nasty concussion," said Hammer.

"It was probably the only way to the idea," I answered. "I tell you the cat is a wizard. He did it on purpose. He's a black magician."
