It also brought us closer to the oncoming Outsiders, and I couldn’t tell which of us would get there first. As I sped up, Karrin dug into the compartments on the Harley, reaching around me, then said, “Hold it steady!”
Then she stood up, and I couldn’t see a damned thing—but I did see the way she pulled the pin out of a freaking hand grenade, and let the spoon spin off into the night. The Harley buzzed past the tugboat’s rig maybe ten feet ahead of the Outsiders, and Karrin gave the grenade a rather feeble little flick as we went by. I heard it smash into glass, like a stone thrown against a window, and then we were past the barge, and a huge sound thudded through the air, like an entire library of books all dropped flat at the same instant, and an incandescent white light flared from the tug.
I looked back over my shoulder and saw that the tugboat was on fire, pouring out thick black smoke and leaning sharply to one side. Murphy saw it, too, and let out an ululating war cry before she sat back down and pushed my hands off the handlebars, reassuming control of the Harley. “Two down!” she said. “One to go!”
