Stands the clock at ten to three?

Around 3 oclock in the moring I am woken by J thundering overhead. "Soozee, there are bats out here. Come and look."

I'd heard skittering on the cabin roof and squeaking: "Let's wake Susan, quicker-licker-lee-hee-hee!" But in the darkness, I couldn't make out more than a brief pale shadow flicking past. I heard them quicksplash in the water. Bats fishing?
