"I don't intend to," I whispered, "but I've got to stop them somehow. We may never get another chance. They must be about through around here."

I broke loose and moved down the gravel road on to the wooden platform. I hadn't the faintest idea of what I was going to do. There wouldn't be time to call the police, and, even if I did, it might not do much good. Nobody outside of the Civic Hospital knew about the biological warfare theory. If I got involved in an argument I might end up in the police station, probably get the flu, and not be able to prove a thing. No, I'd have to handle this myself, play it strictly by ear and wait for the breaks.

The men were busy now over the canvas cover and mooring ropes of a fast-looking pleasure cruiser tied alongside the big jetty, with its bow to the open sea. There were hundreds like it on these waters and it would attract little attention. The short man was directing operations from the dock and his speech was perfect, colloquial American, from somewhere in the Northern United States or Canada.

"This one is probably the leader," I thought. "With an accent like that he could cross the border and never be noticed as he moved about the whole Pacific Northwest."

The fog seemed to be lifting in spots. It was getting lighter and a moon halo could be seen through the drifting clouds of mist. The three men were in a hurry. They didn't notice me until I was opposite their boat.

"I'd like to talk to you," I said to yellow-hair, who was bending over a bollard.

He started and straightened up quickly. I saw his head lift a little more as he got a good look at me.

"I'm busy; what do you want?" he grunted.

"I want something done about the damage to my boat," I said loudly.

The other two had stopped to watch me. At a nod from the leader, the second man went on getting the boat ready. The tall man stepped from the bow on to the main dock so he now stood a little behind yellow-hair and off towards the middle of the dock. I still had a clear line of retreat, but I didn't care for the setup; it isn't good tactics to be out-flanked.
