When I peeked over the parapet at the back, Tara and Joe were below, cupping something hot in Krakatoa’s distinctive paper cups. Their breath fogged the air around them. I scanned up and down the alley, then checked out the side street as well. All seemed clear. I appeared behind Joe, lifted the edge of the mask and said, louder than necessary, “Ready?” “Shit!” he said, jerking around.

Tara put one hand over her mouth. After a second she said, “Ready.” I jumped her to Cory’s lab where she burst out laughing. “That was mean.” I said, through the mask, “Who’s doing the laughing?

You should go get him.
