The bat--or Farold, or Farold in the bat's body--stood motionless for a moment. "That's right," it finally said. "I was murdered. That was how I came to be dead. I remember hearing you call me, and that's why I came back."
"Right," Selwyn said, glad to be back on the topic they needed to be on. "We called you here so that you could tell tell us who did it."
The bat that was Farold said, "I thought you called me here so that you could tell me."
"What?" Elswyth snapped.
"You don't know who killed you?" Selwyn asked in horror.
"I was asleep, you dumb twit. It was the middle of the night, and it was dark, and"--the bat beat at Selwyn's hand with its wings, as though forgetting that it had wings, and not hands--"if you had looked before starting all this, you would have seen that I was stabbed in the back."
Selwyn rested his forehead on the palm of his hand.
